Relax Already: Find Calm Through Family Photos

FitSugar — Fri, 05 Dec 2008 15:30:00 -0800

Sometimes it seems like the more effort we put into shutting down our busy brains, the harder it is to accomplish. Jam-packed, stressful days make true relaxation challenging for many of us, and we often forgo winding down after work because of time demands. If taking a 90-second vacation doesn't always work for you, look through pictures from previous vacations to help get you to a state of relaxation.

While you are flipping through those memories, try your best to recall the little things you loved about a particular trip: special moments shared with your friends or loved ones, things that made you laugh, and the happy feeling of getting away from it all. The simple act of revisiting your memories will take your mind off of your hectic day and to-do list while reminding you of the good things in your life.

Class Act: Yoga Nidra (Yoga Sleep)

FitSugar — Thu, 04 Sep 2008 14:30:00 -0700

If you're stressed out, wound up, or feeling down, then you're in desperate need of Yoga Nidra. It's the definition of deep relaxation.

The nidra class is devoted to bringing you into complete stillness and calmness while still being aware. You come into a comfortable Savasana pose (sometimes a teacher may encourage you to use blankets and pillows to make you feel comfy, cradled, and fully supported). The teacher may talk you through a meditation, use guided imagery, or she may use musical instruments or music to bring you into deep relaxation. Your job is to lengthen each inhale and exhalation, to be aware and in control of your breath, and to allow the stillness to take over your mind and unwind your nervous system. It's common for beginners to accidentally fall asleep, but once you practice Yoga Nidra more often, you'll become better at bringing yourself into a beautiful marriage of relaxation and awareness. It's normal to daydream a little, to experience a sense of weightlessness or floating above the ground, and many people will say they feel like the 45 or 60 minute class flies by within minutes. After the class, you'll emerge feeling refreshed and serene.

Call a yoga studio in your area to see if they offer this type of class. If you cannot find a class, you can try on your own with a book or CD.

Relax Already: Active Relaxation

FitSugar — Thu, 19 Apr 2007 17:15:00 -0700

I know that it seems like a contradiction of terms, but active relaxation is a real technique for getting rid of unwanted tension. Stress creates muscle tension so actively relaxing your muscles can really help clear your mind and ease your level of anxiety.

Hold the following positions for 5 seconds and focus on the sensation of muscle tightness. Then actively release the position and focus on the sensation of tension leaving the muscles. These moves can be done sitting at your desk and I recommend doing them each a couple of times.

Lower body:
(Start with your right foot, then repeat on the left side)

Scrunch your toes and point your toes inward
Flex your toes and pull them toward your head
Straighten your knee, so leg is parallel to the floor and tense your thigh, relax the leg back down

For your torso:

Squeeze your bum
Tense your stomach, make it feel tight like a ball
Squeeze your shoulder blades together

To see what else you can do for your shoulders just read more

For your arms and shoulders:

Make fists with both hands
Squeeze your arms into your sides
Raise your shoulders to your ears

For your face and neck:

Squint your eyes and wrinkle your nose
Pull your lips in
Open your mouth as wide as you can
Raise your eyebrows as high as you can

Now I know the facial "moves" are quite conspicuous, so they might be hard to get away with in a small office, but they are great for your car ride home. Once you tense and relax all these muscles, you should feel both an ease of body and mind. So go on, relax already.

Relax Already: Get an Aston Patterning Massage

FitSugar — Fri, 07 Dec 2007 09:30:00 -0800

With all the hustle and bustle of the holidays, it is important to make sure you fit in a little "you time" every now and again. I was given the opportunity for some serious "me time" during a recent Aston Patterning Massage (APM) session compliments of Tre Balm Beauty Boutique and Skin Care Studio here in San Francisco and let me tell you, it was much needed.

For anyone that has never had this type of massage before, APM is basically a massage technique that combines deep tissue work, massage, and movement all in one. Don't be surprised if you hear the occasional bell ring, your leg gets turned in directions you never knew it could, or if you find your massage therapist on top of the table pulling your arms into the air - it's all part of the treatment. I tend to be a little OCD when I am getting a massage and will calculate what is going to happen next, but APM therapists make the most of unique body types rather than trying to force them to conform to an ideal, so each movement is totally different. Sure it may sound a little wacky, but I left my session feeling absolutely amazing and totally refreshed. I went in worrying about holiday presents, travel, and work but by the time my appointment was over I had forgotten it all.

Not only is it a fabulous way to relax, but APM can also minimize the dreaded effects of repetitive movements on the body that many people experience on a daily basis, like say, sitting at a desk and typing all day. If you live here in San Francisco I highly suggest setting up an appointment with Tre Balm (and Nadja, the fabulous massage therapist), but if not then be sure check with your local spa to find out if they offer APM.

Relax Already: Thai Yoga Massage

FitSugar — Mon, 08 Oct 2007 16:45:00 -0700

The latest in relaxation involves a little more work than just laying on a massage table and getting rubbed down.

Thai Yoga Massage (some people call it "Thai Massage" only) is a massage where the practitioner guides the recipient through a series of yoga postures while massaging along the body's pressure points. Ultimately it is a full body massage performed on a floor mat with a practitioner who uses hands, feet, arms, and legs to guide the client into various yoga postures. Why, you ask? Well Thai Yoga Massage has been said to relieve muscular tension, improve circulation, boost the immune system and strengthen flexibility. All while burning a few more calories than a regular massage, I can imagine. Not a yogi? No problem because no previous experience with yoga is needed by the client. I still can't decide if it looks painful or relaxing, but I'm willing to give it a shot.

Right now it is being offered at the Nicolas Christies Day Spa in Massachusetts, but visit ThaiYoga.com for a list of therapists near you.

Relax Already: Meditate

FitSugar — Mon, 04 Dec 2006 17:35:00 -0800

Being stressed out can have negative effects on your body and your self esteem. One way to alleviate stress is to meditate. If that sounds too woo woo for you, well read on and see just how simple it is.

First you want to sit or lie in a comfortable position. Then close your eyes and breathe deeply, smoothly and slowly. Focus all your attention on this simple action (that might be a lot harder than it sounds). When your mind wanders, which it inevitably will, bring your focus back to your breath.

If you need something to help you focus your mind, pick a short mantra to repeat in your head and try to coordinate it with your breath pattern. On the inhale say "I am feeling" and the exhale say "Calm" or "Patient" (that is a big one for me). Make your own mantra - I'd love to hear what works for you.

Fit's Tip: Start small - one minute in the morning and one minute in the afternoon. Or try for five minutes: Set your alarm for five minutes, close your eyes and just focus on "being."

HEALTH GUIDE REFERENCE FROM A.D.A.M

Highlights

Some people are pre-programmed for a heightened response to stress by conditions in the womb. Pregnant women under stress who eat a diet high in protein and low in carbohydrates have babies with higher cortisol levels. Later on, these levels increase in response to stress.
The impact of stress on the heart and circulation system is becoming more clear. Stress causes the body to release inflammatory markers that may worsen heart and circulatory diseases as well as inflammatory disease, such as rheumatoid arthritis. High levels of inflammatory markers are associated with increased risk of heart attack and stroke. Extreme stress can also produce a condition that mimics a heart attack, but is reversible. People under severe stress can experience irregular heart beats that make them susceptible to sudden cardiac death.
Stress also increases the risk of developing type 2 diabetes in women.
Traumatic stress has long been known to cause amnesia, emotional numbness, nightmares, and memory problems. Now it is known that traumatic emotional stress can cause permanent changes in the brain that interfere with the normal way information is accepted, coded, and retrieved.
The good news is that our physical response to stress is increasingly understood. Knowing what occurs at the cellular level may help researchers find more ways to counteract the detrimental physical and emotional effects of stress.

Introduction

Stress affects most people in some way. Acute (sudden, short-term) stress leads to rapid changes throughout the body. Almost all body systems (the heart and blood vessels, the immune system, the lungs, the digestive system, the sensory organs, and brain) gear up to meet the perceived danger.

These stresses could prove beneficial in a critical, life-or-death situation. Over time, however, repeated stressful situations put a strain on the body that may contribute to physical and psychological problems. Chronic (long-term) stress can have real health consequences and should be addressed like any other health concern.

Fortunately, research is showing that lifestyle changes and stress-reduction techniques can help people learn to manage their stress.

People can experience stress from external or internal factors.

External stressors include adverse physical conditions (such as pain or hot or cold temperatures) or stressful psychological environments (such as poor working conditions or abusive relationships). Humans, like animals, can also experience external stressors.
Internal stressors can also be physical (infections, inflammation) or psychological (such as intense worry about a harmful event that may or may not occur). As far as anyone can tell, internal psychological stressors are rare or absent in most animals except humans.

Stressors can also be defined as short-term (acute) or long-term (chronic).

Acute Stress. Acute stress is the reaction to an immediate threat, commonly known as the fight or flight response. The threat can be any situation that is perceived, even subconsciously or falsely, as a danger.

Common acute stressors include:

Noise (which can trigger a stress response even during sleep)
Crowding
Isolation
Hunger
Danger
Infection
High technology effects (playing video games, frequently ringing mobile phones)
Imagining a threat or remembering a dangerous event

Under most circumstances, once the acute threat has passed, levels of stress hormones return to normal. This is called the relaxation response.

Chronic Stress. Frequently, modern life poses ongoing stressful situations that are not short-lived. The urge to act (to fight or flee) must therefore be controlled. Stress, then, becomes chronic.

Common chronic stressors include:

On-going highly pressured work
Long-term relationship problems
Loneliness
Persistent financial worries

The Body's Response

The best way to envision the effect of acute stress is to imagine yourself in a primitive situation, such as being chased by a bear.

In response to seeing the bear, a part of the brain called the hypothalamic-pituitary-adrenal (HPA) system is activated.

Release of Steroid Hormones and the Stress Hormone Cortisol. The HPA systems trigger the production and release of steroid hormones (glucocorticoids), including the primary stress hormone cortisol. Cortisol is very important in organizing systems throughout the body (including the heart, lungs, circulation, metabolism, immune systems, and skin) to deal quickly with the bear.

Release of Catecholamines. The HPA system also releases certain neurotransmitters (chemical messengers) called catecholamines, particularly those known as dopamine, norepinephrine, and epinephrine (also called adrenaline).

Catecholamines activate an area inside the brain called the amygdala, which appears to trigger an emotional response to a stressful event. In the case of the bear, this emotion is most likely fear.

Release of Neuropeptide S. The brain releases neuropeptide S, a small protein that modulates stress by decreasing sleep and increasing alertness and a sense of anxiety. This gives the person a sense of urgency to run away from the bear.

Effects on Long- and Short-Term Memory. During the stressful event, catecholamines also suppress activity in areas at the front of the brain concerned with short-term memory, concentration, inhibition, and rational thought. This sequence of mental events allows a person to react quickly, either to fight the bear or to flee from it. It also interferes with the ability to handle difficult social or intellectual tasks and behaviors during that time.

On the other hand, neurotransmitters at the same time signal the hippocampus (a nearby area in the brain) to store the emotionally loaded experience in long-term memory. In primitive times, this brain action would have been essential for survival, since long-lasting memories of dangerous stimuli (such as the large bear) would be critical for avoiding such threats in the future.

The stress response also affects the heart, lungs, and circulation:

As the bear comes closer, the heart rate and blood pressure increase instantaneously.
Breathing becomes rapid, and the lungs take in more oxygen.
The spleen discharges red and white blood cells, allowing the blood to transport more oxygen throughout the body. Blood flow may actually increase 300 - 400%, priming the muscles, lungs, and brain for added demands.

The effect on the immune system from confrontation with the bear is similar to organizing a defensive line of soldiers to potentially critical areas. The steroid hormones reduce the activity in parts of the immune system, so that specific infection fighters (including important white blood cells) or other immune molecules can be repositioned. These immune-boosting troops are sent to the body's front lines where injury or infection is most likely to occur, such as the skin and the lymph nodes.

As the bear gets closer, fluids are diverted from nonessential locations, including the mouth. This causes dryness and difficulty in talking. In addition, stress can cause spasms of the throat muscles, making it difficult to swallow.

The stress effect moves blood flow away from the skin to support the heart and muscle tissues. This also reduces blood loss in the event that the bear causes a wound. The physical effect is a cool, clammy, sweaty skin. The scalp also tightens so that the hair seems to stand up.

Stress shuts down digestive activity, a nonessential body function during short-term periods of hard physical work or crisis.

Once the threat has passed and the effect has not been harmful (for example, the bear has not wounded the human), the stress hormones return to normal. This is known as the relaxation response. In turn, the body's systems also return to normal.

Complications

In prehistoric times, the physical changes in response to stress were an essential adaptation for meeting natural threats. Even in the modern world, the stress response can be an asset for raising levels of performance during critical events, such as a sports activity, an important meeting, or in situations of actual danger or crisis.

If stress becomes persistent and low-level, however, all parts of the body's stress apparatus (the brain, heart, lungs, vessels, and muscles) become chronically over- or under-activated. Such chronic stress may produce physical or psychological damage over time. Acute stress can also be harmful in certain situations, particularly in individuals with preexisting heart conditions.

Studies suggest that the inability to adapt to stress is associated with the onset of depression or anxiety. In one study, two-thirds of subjects who experienced a stressful situation had nearly 6 times the risk of developing depression within that month.

Some evidence suggests that repeated release of stress hormones produces hyperactivity in the hypothalamic-pituitary-adrenal (HPA) system, and disrupts normal levels of serotonin, the nerve chemical that is critical for feelings of well-being. Some people appear to be more at risk for an overactive HPA system under stress, including those with the personality traits that cause perfectionism. Certainly, on a more obvious level, stress reduces the quality of life by reducing feelings of pleasure and accomplishment. In addition, relationships are often threatened in times of stress.

The full impact of mental stress on heart disease is just coming to light, but the underlying mechanisms are not always clear. Stress can certainly influence the activity of the heart when it activates the automatic part of the nervous system that affects many organs, including the heart. Such actions and others could theoretically affect the heart badly in several ways:

Sudden stress increases the pumping action and rate of the heart, while at the same time causing the arteries to constrict (narrow). This restricts blood flow to the heart. A 2002 study suggested that such actions may be responsible for some cases of acute stress that have been associated with a higher risk for serious heart problems. These problems include heart rhythm abnormalities and heart attacks, and even death in people with heart disease.
Emotional effects of stress alter the heart rhythms, which could pose a risk for serious arrhythmias (rhythm abnormalities) in people with existing heart rhythm disturbances.
Stress causes blood to become stickier (possibly in preparation of potential injury), increasing the likelihood of an artery-clogging blood clot.
Stress appears to impair the clearance of fat molecules in the body, raising blood-cholesterol levels, at least temporarily.
Stress that leads to depression appears to be associated with increased intima-medial thickness, a measure of the arteries that signifies worsening blood vessel disease.
Chronic stress may lead to the production of immune factors called cytokines, although study results vary widely. Cytokines produce an inflammatory response that is now believed to be responsible for damaging the arteries. Such damage contributes to heart disease. New studies indicate that some people under stress may have increased levels of C-reactive protein (CRP), a risk marker for heart attack. Each 1 mg/L increase in CRP has been linked to a 20% increased risk of myocaridal ischemia, a condition that signals poor blood flow to the heart muscle.
Stress causes the body to release inflammatory markers into the bloodstream. These markers may worsen heart disease or increase the risk of heart attack or stroke.
Studies have reported an association between stress and high blood pressure, which may be more pronounced in men than in women. According to some evidence, people who regularly experience sudden spikes in blood pressure (caused by mental stress) may, over time, develop injuries in the inner lining of their blood vessels. In one 20-year study, for example, men who periodically measured highest on the stress scale were twice as likely to have high blood pressure as those with normal stress.

Evidence is still needed to confirm any clear-cut relationship between stress and heart disease. For example, a 2002 study in Scotland found no greater risk for actual heart disease or heart events even in men who reported higher mental stress. In fact, higher stress was associated with fewer heart events. Men with high stress levels did tend to complain of chest pain and to go to the hospital for it more often than those with lower stress. They also went to the hospital more often.

Evidence links stress to heart disease in men, particularly in work situations where they lack control. The association between stress and heart problems in women is weaker, and there is some evidence that the ways women cope with stress may be more heart-protective. In one study, men were more apt than women to use alcohol or eat less healthily in response to stress, which might account for their higher heart risks from stress. Different stressors may affect genders differently. In one study, work stress was associated with a higher risk for heart disease in men, but marital stress -- not work stress -- was associated with more severe heart disease in women with existing heart problems.

A condition called stress cardiomyopathy (or Takotsubo cardiomyopathy) is widely recognized. In this disease, intense emotional or physical stress causes severe but reversible heart dysfunction. The patient experiences chest pain, and EKGs and echocardiograms indicate a heart attack, but further tests show no underlying obstructive coronary artery disease.

Acute emotional stress can create abnormal heartbeats. MRI studies show that asymmetric brain activity may play a role in making a stressed heart susceptible to ventricular arrhythmias by creating electrical instability. In some patients, this can cause sudden cardiac death.

Psychological stress is also recognized as a possible cause of acute coronary syndrome (ACS), a collection of symptoms that signify heart attack or approaching heart attack. In one study of men who suffered ACS at work or up to 2 hours after work, many of the men were found to have anger and negative emotions. A 2007 review of studies on blood qualities, coagulation, fibrinolysis, and platelet reactivity found that high levels of psychological stress are associated with harmful changes to the blood. The research suggests that stress has the potential to trigger ACS, particularly in patients with heart disease. The studies also suggest that the risk is greatest immediately after the stressful incident, rather than during it.

Stress Reduction and Heart Disease. Studies suggest that treatments that reduce psychological distress improve long-term outlook in people with heart disease, including after a heart attack. Evidence indicates that stress management programs may reduce the risk of heart attacks by up to 75% in people with heart disease. Specific stress management techniques may help some problems but not others. For example, acupuncture in one study helped people with heart failure but had no effect on blood pressure. Relaxation methods, on the other hand, may help people with high blood pressure.

One survey revealed that men who had a more intense response to stressful situations, such as waiting in line or problems at work, were more likely to have strokes than those who did not report such distress. In some people, prolonged or frequent mental stress causes an exaggerated increase in blood pressure.

Chronic stress affects the immune system in complicated ways, and may have various results.

Susceptibility to Infections. Chronic stress appears to blunt the immune system's response to infections, and may even impair a person's response to immunizations. Several studies have shown that people under chronic stress have low white blood cell counts and are vulnerable to colds. Once a person catches a cold or flu, stress can make symptoms worse. People who carry the herpes virus or HIV may be more susceptible to viral activation following exposure to stress. Even more serious, some research has found that HIV-infected men with high stress levels progress more rapidly to AIDS when compared to those with lower stress levels.

Inflammatory Response. Some evidence suggests that chronic stress triggers an over-production of certain immune factors called cytokines. In excess levels, these chemicals can have very damaging effects. A recent study found that students unable to cope with stress had high levels of TNF-alpha, an inflammatory cytokine. Such findings may partly explain the association between chronic stress and numerous diseases, including heart disease and asthma.

Whether or not stress causes or aggravates cancer is not entirely clear. One study reported no association between stressful life events and recurrence in women who had been treated for breast cancer. Nevertheless, some animal studies suggest that lack of control over stress (not simply stress itself) had negative effects on immune function and contributed to tumor growth.

That being said, a 2007 study found that stress activates a gene that may cause metastatic cancer, as measured by increasing levels of the marker AGR2.

Although stress reduction techniques have no effect on survival rates, studies show that they are very helpful in improving a cancer patient's quality of life. Stress is also known to be one cause of hyponatremia (low plasma sodium levels) in cancer patients. Fortunately, this imbalance can be corrected with drugs called AVP-receptor agonists, developed for use in heart failure.

The brain and intestines are strongly related, and are controlled by many of the same hormones and parts of the nervous system. Indeed, some research suggests that the gut itself has features of a primitive brain. It is not surprising then that prolonged stress can disrupt the digestive system, irritating the large intestine and causing diarrhea, constipation, cramping, and bloating. Excessive production of digestive acids in the stomach may cause a painful burning.

Irritable Bowel Syndrome. Irritable bowel syndrome (or spastic colon) is strongly related to stress. With this condition, the large intestine becomes irritated, and its muscular contractions are spastic rather than smooth and wave-like. The abdomen is bloated, and the patient experiences cramping and alternating periods of constipation and diarrhea. Sleep disturbances due to stress can make irritable bowel syndrome even worse.

Peptic Ulcers. It is now well-established that most peptic ulcers are either caused by the H. pylori bacteria or the use of nonsteroidal anti-inflammatory (NSAID) medications (such as aspirin and ibuprofen). Nevertheless, studies still suggest that stress may predispose someone to ulcers, or sustain existing ulcers. Some experts estimate that social and psychological factors play some contributing role in 30 - 60% of peptic ulcer cases, whether they are caused by H. pylori or NSAIDs. In any case, some experts believe that the anecdotal relationship between stress and ulcers is so strong that attention to psychological factors is still warranted.

Inflammatory Bowel Disease. Although stress is not a cause of inflammatory bowel disease (Crohn's disease or ulcerative colitis), there are reports of an association between stress and symptom flare-ups. One study, for example, found that while short-term (over the previous month) stress did not significantly exacerbate ulcerative colitis symptoms, long-term perceived stress tripled the rate of flare-ups compared to patients who did not report feelings of stress.

Stress can have varying effects on eating problems and weight.

Weight Gain. Often stress is related to weight gain and obesity. Many people develop cravings for salt, fat, and sugar to counteract tension. As a result, they gain weight. Weight gain can occur even with a healthy diet, however, in some people exposed to stress. In addition, the weight gained is often abdominal fat, a predictor of diabetes and heart problems.

The release of cortisol, a major stress hormone, appears to encourage abdominal fat and may be the primary connection between stress and weight gain. Cortisol is a glucocorticoid. These hormones, along with insulin, appear to be responsible for stress-related food cravings. A 2005 study showed that hormonally induced cravings for "comfort foods" may have a biological benefit for managing stress. Eating comfort foods appears to reduce the negative hormonal and behavioral changes associated with stress, which might lessen the impact of stress on an individual. Carbohydrates in particular have been found to significantly increase levels of tryptophan and large neutral amino acids. This produces serotonin, which improves mood and performance under stress.

A 2007 study proposes a "reward-based stress eating" model. In this theory, stress and tasty, high-calorie foods cause the brain to make chemicals called endogenous opioids. These neurotransmitters help protect against the harmful effects of stress by slowing activity of a brain process called the hypothalamic-pituitary-adrenal (HPA) axis, thus weakening the stress response. Repeated stimulation of the reward pathways through stress-induced HPA stimulation, eating tasty food, or both, may lead to changes in the brain that cause compulsive overeating.

Weight Loss. Some people suffer a loss of appetite and lose weight during periods of stress. In rare cases, stress may trigger hyperactivity of the thyroid gland, stimulating appetite but causing the body to burn up calories at a faster than normal rate.

Eating Disorders. Chronically elevated levels of stress chemicals have been observed in patients with anorexia and bulimia. Some studies, however, have not found any strong link between stress and eating disorders. More work is needed to determine if changes in stress hormones are a cause or result of eating disorders.

Chronic stress has been associated with the development of insulin resistance, a condition in which the body is unable to use insulin effectively to regulate glucose (blood sugar). Insulin resistance is a primary factor in diabetes. In the Healthy Women Study, a large population of healthy women was studied for 15 years. Very stressful life events and severe depression greatly increased the risk of developing insulin resistance.

In another study of more than 33,000 Swedish workers, the development of type 2 diabetes was strongly correlated with work stress and low emotional support. However, the effect was seen in women, but not in men.

Stress can also exacerbate existing diabetes by impairing the patient's ability to manage the disease effectively.

Researchers are attempting to find the relationship between pain and emotion, but the area is complicated by many factors, including effects of personality types, fear of pain, and stress itself. A recent study suggests that chronic pain may impair the action of neutrophils, thereby weakening the immune response.

Muscular and Joint Pain. Stress may intensify chronic pain caused by arthritis and other conditions. According to a study on patients with rheumatoid arthritis, however, stress management techniques do not appear to have much effect on arthritic pain. Psychological distress also plays a significant role in the severity of back pain. Some studies have clearly associated job dissatisfaction and depression to back problems, although it is still unclear if stress is a direct cause of the back pain.

Headaches. Tension-type headaches are highly associated with stress and stressful events. Sometimes the headache does not start until long after the stressful event has ended. Additionally, stress can contribute to the development of headaches or cause headaches to occur more often.

Some research suggests that people who suffer from tension-type headaches may have some biological predisposition for translating stress into muscle contractions. Among the wide range of possible migraine triggers is emotional stress (although the headaches often erupt after the stress has eased). One study suggested that women with migraines tend to have personalities that over-respond to stressful situations.

The tensions of unresolved stress frequently cause insomnia, generally keeping the stressed person awake or causing awakening in the middle of the night or early morning. This appears to be due to the fact that stress causes physiological arousal during non-rapid eye movement (NREM) sleep.

Sexual Function. Stress can lead to diminished sexual desire and an inability to achieve orgasm in women. Stress response can cause androgen levels to drop, causing temporary impotence in men. Part of the stress response involves the release of brain chemicals that constrict the smooth muscles of the penis and its arteries. This constriction reduces the blood flow into and increases the blood flow out of the penis, which can prevent erection.

Premenstrual Syndrome. Some studies indicate that the stress response in women with premenstrual syndrome may be more intense than in those without the syndrome.

Fertility. Stress may even affect fertility. Stress hormones have an impact on the hypothalamus gland, which produces reproductive hormones. Severely elevated cortisol levels can even shut down menstruation. One small study reported a significantly higher incidence of pregnancy loss in women who had both high stress and prolonged menstrual cycles. Another reported that women with stressful jobs had shorter periods than women with low-stress jobs.

Effects on Pregnancy. Old wives' tales about a pregnant woman's emotions affecting her baby may have some credence. Stress may cause physiologic alterations, such as increased adrenal hormone levels or resistance in the arteries, which may interfere with normal blood flow to the placenta. Maternal stress during pregnancy has been linked to a higher risk for miscarriage, lower birth weights, and increased incidence of premature births. Some evidence also suggests that stress experienced by expectant mothers can even influence the way in which the baby's brain and nervous system will react to stressful events. Indeed, one study found a higher rate of crying and low attention in infants of mothers who had been stressed during pregnancy.

Menopause. A drop in estrogen levels during perimenopause and menopause may be responsible for changes in mood precipitated by stress. Estrogen replacement therapy can soften this response to stressful events.

Stress affects the brain, particularly memory, but the effects vary widely depending on whether the stress is acute or chronic.

Effect of Acute Stress on Memory and Concentration. Studies indicate that the immediate effect of acute stress impairs short-term memory, particularly verbal memory. On the plus side, high levels of stress hormone during short-term stress have been associated with enhanced memory storage and greater concentration on immediate events. The difference in effect may be due to how cortisol impacts glucocorticoid receptors in the hippocampus and prefrontal cortex. In a study of 20 men and 20 women, those whose cortisol levels increased in response to unpleasant, emotionally arousing photos had less memory recall later than those whose cortisol levels did not rise.

Effect of Chronic Stress on Memory. If stress becomes chronic, sufferers often experience loss of concentration at work and home, and they may become inefficient and accident-prone. In children, the physiologic responses to chronic stress can clearly inhibit learning. Chronic stress in older people may play an even more important role in memory loss than the aging process. In one study, for example, older adults with low stress hormone levels tested as well as younger adults in cognitive tests; those with higher stress levels tested 20 - 50% lower.

Studies have connected long-term exposure to excess amounts of cortisol (a major stress hormone) to shrinking of the hippocampus, the brain’s memory center. For example, two studies reported that groups who suffered from post-traumatic stress disorder (Vietnam veterans and women who suffered from sexual abuse) displayed up to 8% shrinking of the hippocampus. It is not yet known if this shrinking is reversible.

Allergies. Stress has been related to skin allergies. Some research suggests that stress, not indoor pollutants, may actually be a cause of the so-called sick-building syndrome. Sick-building syndrome produces allergy-like symptoms, such as eczema, headaches, asthma, and sinus problems, in office workers.

Compulsive Hoarding. People with obsessive-compulsive disorder (OCD) and compulsive hoarding are far more likely to have experienced a traumatically stressful event than people with OCD who are not hoarders. Hoarders who have experienced traumatic events have significantly more severe hoarding than those who have not been traumatized. The strongest association with traumatic stress is found in the clutter factor of compulsive hoarding, rather than in difficulty discarding objects.

Chronic Fatigue. Stress increases the risk of developing chronic fatigue syndrome, although studies suggest that high levels of emotional instability may genetically predispose someone to the syndrome.

Skin Disorders. Stress plays a role in worsening numerous skin conditions, including hives, psoriasis, acne, rosacea, and eczema, and is one of the most common causes of eczema. Unexplained itching may also be caused by stress. Evidence suggests that experiencing the stress of a traumatic event (parental divorce or separation, or a severe disease in a family member) before age 2 increases the risk of developing eczema.

Unexplained Hair Loss (Alopecia Areata). Alopecia areata is hair loss that occurs in localized (individual) patches. The cause is unknown, but stress is suspected as a player in this condition. For example, hair loss often occurs during periods of intense stress, such as mourning.

Teeth and Gums. Stress has now been implicated in increasing the risk for periodontal disease, which is disease in the gums that can cause tooth loss.

People under chronic stress often turn to alcohol abuse or tobacco use for relief. The damage these self-destructive habits cause under ordinary circumstances is compounded by the physiological effects of stress itself. Many people also resort to abnormal eating patterns or passive activities, such as watching television. The results of a national survey, released in February 2006, show that: "Americans engage in unhealthy behaviors such as comfort eating, poor diet choices, smoking and inactivity to help deal with stress."

Alcohol affects receptors in the brain that reduce stress. Lack of nicotine increases stress in smokers, which creates a cycle of dependency on smoking. One study indicated that nicotine has calming effects in women but not in men. In fact, in the study, smoking increased aggression in men.

The cycle is self-perpetuating: a sedentary routine, an unhealthy diet, alcohol abuse, and smoking all promote heart disease. They also interfere with sleep patterns, and lead to increased rather than reduced tension levels. Drinking four or five cups of coffee, for example, can cause changes in blood pressure and stress hormone levels similar to those produced by chronic stress. Animal fats, simple sugars, and salt are known contributors to health problems.

Conditions with Similar Symptoms

The physical symptoms of anxiety disorders mirror many symptoms of stress, including:

A fast heart rate
Rapid, shallow breathing
Increased muscle tension

Anxiety is an emotional disorder, however, and is characterized by feelings of apprehension, uncertainty, fear, or panic. Unlike stress, the triggers for anxiety are not necessarily or even usually associated with specific stressful or threatening conditions. Some individuals with anxiety disorders have numerous physical complaints, such as headaches, gastrointestinal disturbances, dizziness, and chest pain. Severe cases of anxiety disorders are debilitating, and interfere with career, family, and social spheres.

Depression can be a disabling condition, and, like anxiety disorders, may result from chronic stress. A 2005 study of Canadian workers found that individuals with a high level of work-related stress are more than twice as likely to experience a major depressive episode, compared with people under less stress. Evidence also suggests that certain people may be genetically susceptible to depression after stressful life events. Depression also mimics some of the symptoms of stress, including changes in appetite, sleep patterns, and concentration. Serious depression, however, is distinguished from stress by feelings of sadness, hopelessness, loss of interest in life, and, sometimes, thoughts of suicide. Acute depression is also accompanied by significant changes in the patient's functioning. Professional therapy may be needed in order to determine if depression is caused by stress, or if it is the primary problem.

Post-traumatic stress disorder (PTSD) is a reaction to a very traumatic event, and it is actually classified as an anxiety disorder. The event that brings on PTSD is usually outside the norm of human experience, such as intense combat or sexual assault. The patient struggles to forget the traumatic event and frequently develops emotional numbness and event-related amnesia. Often, however, there is a mental flashback, and the patient re-experiences the painful circumstance in the form of dreams and disturbing thoughts and memories. These thoughts and dreams resemble or recall the trauma. Other symptoms may include lack of pleasure in formerly enjoyed activities, hopelessness, irritability, mood swings, sleep problems, inability to concentrate, and an excessive startle-response to noise.

Treatment

Perhaps the best general approach for treating stress can be found in the elegant passage by Reinhold Niebuhr, "Grant me the courage to change the things I can change, the serenity to accept the things I can't change, and the wisdom to know the difference." The process of learning to control stress is life-long, and will not only contribute to better health, but a greater ability to succeed in one's own agenda.

Stress can be a factor in a variety of physical and emotional illnesses, which should be professionally treated. Many stress symptoms are mild and can be managed by over-the-counter medications (for example, aspirin, acetaminophen, or ibuprofen for tension headaches; antacids, anti-diarrhea medications, or laxatives for mild stomach distress). A physician should be consulted, however, for physical symptoms that are out of the ordinary, particularly those that get worse or wake a person up at night. A mental health professional should be consulted for unmanageable acute stress or for severe anxiety or depression. Often short-term therapy can resolve stress-related emotional problems.

In choosing specific strategies for treating stress, several factors should be considered.

No single method is always successful: A combination of approaches is generally most effective.
What works for one person does not necessarily work for someone else.
Stress can be positive as well as negative. Appropriate and controllable stress provides interest and excitement and motivates the individual to greater achievement. A lack of stress may lead to boredom and depression.

Stress may play a part in making people vulnerable to illness. A physician or psychologist should be consulted if there are any indications of accompanying medical or psychological conditions, such as heart symptoms, significant pain, anxiety, or depression.

People often succeed in relieving stress for the short term. However, they go back to previous ways of stressful thinking and behaving because of outside pressure, long-held beliefs, or habits. The following are some obstacles to managing stress:

The fight or flight urge: The very idea of relaxation can feel threatening, because it is perceived as letting down one's guard. For example, an over-demanding boss may put a subordinate into a psychological state of fighting-readiness, even though there is no safe opportunity for the subordinate to fight back or express anger. Stress builds up, but the worker has the illusion, even subconsciously, that the stress itself is providing safety or preparedness. For this reason, the employee does nothing to correct the condition.
Many people are afraid of being perceived as selfish if they engage in stress-reducing activities that benefit only themselves. The truth is that self-sacrifice (in the form of not reducing one’s stress) may be inappropriate and even damaging, if the person making the sacrifice is unhappy, angry, or physically unwell.
Some people believe that certain emotional responses to stress, such as anger, are natural and unchangeable features of personality. Research has shown, however, that with cognitive behavioral therapy, individuals can be taught to change their emotional reactions to stressful events.

It is essential to remember that reducing stress and staying relaxed clears the mind, so it can begin appropriate actions to get rid of the stress-ridden conditions.

Although treating stress cannot cure medical problems, stress management can be a very important part of medical treatment. Specific stress reduction approaches may benefit different medical problems. For example, acupuncture in one study helped reduce harmful heart muscle actions in people with heart failure, but it had no effect on blood pressure. Relaxation methods, on the other hand, may help people with high blood pressure. Stress reduction may improve well-being and quality of life for many patients who are experiencing stress because of severe or chronic medical conditions.

Important Note: Never use stress reduction techniques as the only treatment, or in place of proven treatments, for any medical condition.

Risk Factors

At some point in their lives virtually everyone will experience stressful events or situations that overwhelm their natural coping mechanisms. In one poll, 89% of respondents indicated that they had experienced serious stress in their lives. Some people are simply biologically prone to stress. Many outside factors influence susceptibility as well.

Conditions Most Likely To Produce Stress-Related Health Problems. Conditions that are most likely to be associated with stress and negative physical effects include the following:

An accumulation of persistent stressful situations, particularly those that a person cannot easily control (for example, high-pressured work plus an unhappy relationship)
Persistent stress following a severe acute response to a traumatic event (such as an automobile accident)
Acute stress accompanying serious illness, such as heart disease

Factors That Influence the Response to Stress. People respond to stress differently, depending on different factors:

Early nurturing: Abusive behavior towards children may cause long-term abnormalities in the hypothalamus-pituitary system, which regulates stress.
Personality traits: Certain people have personality traits that cause them to over-respond to stressful events.
Genetic factors: Some people have genetic factors that affect stress, such as having a more or less efficient relaxation response. One study found a genetic abnormality in serotonin regulation that was connected with a heightened reaction of heart rates and blood pressure in response to stress. (Serotonin is a brain chemical involved with feelings of well-being.)
Immune regulated diseases: Certain diseases that are associated with immune abnormalities (such as rheumatoid arthritis or eczema) may actually weaken a response to stress.
The length and quality of stressors: Naturally, the longer the duration and more intense the stressors, the more harmful the effects.

Individuals at Higher Risk for Stress. Studies indicate that the following people are more vulnerable to the effects of stress than others:

Older adults: As people age, achieving a relaxation response after a stressful event becomes more difficult. Aging may simply wear out the systems in the brain that respond to stress, so that they become inefficient. The elderly, too, are very often exposed to major stressors such as medical problems, the loss of a spouse and friends, a change in a living situation, and financial worries. No one is immune to stress, however, and it may simply go unnoticed in the very young and old.
Women in general and working mothers specifically: Working mothers, regardless of whether they are married or single, face higher stress levels and possibly adverse health effects, most likely because they bear a greater and more diffuse work load than men or other women. This has been observed in women in the U.S. and in Europe. Such stress may also have a domino and harmful effect on their children. It is not clear, however, if stress has the same adverse effects on women's hearts as it does on men's.
Less educated individuals.
Divorced or widowed individuals: Numerous studies indicate that unmarried people generally do not live as long as their married contemporaries.
Anyone experiencing financial strain, particularly long-term unemployed and those without health insurance.
People who are isolated or lonely.
People who are targets of racial or sexual discrimination.
People who live in cities.

Children are frequent victims of stress because they are often unable to communicate their feelings accurately. They also have trouble communicating their responses to events over which they have no control. Certain physical symptoms, notably repeated abdominal pain without a known cause, may be indicators of stress in children.

Various conditions can affect their susceptibility to stress.

Low Birth Weight. One study reported that low birth weight and slow growth up until age 7 was related to stress in adulthood.

Parental Stress. Parental stress, especially in mothers, is a particularly powerful source of stress in children, even more important than poverty or overcrowding. In a 2002 study, for example, young children of mothers who were highly stressed (particularly if they were depressed) tended to be at high risk for developing stress-related problems. This was especially true if the mothers were stressed during both the child's infancy and early years. Some evidence even supports the old idea that stress during pregnancy can have adverse effects on the infant's mood and behavior. Older children with stressed mothers may become aggressive and anti-social. One study suggested that stress-reduction techniques in parents may improve their children's behavior.

Gender Differences in Adolescent Stress. Adolescent boys and girls experience equal amounts of stress, but the source and effects may differ. Girls tend to become stressed from interpersonal situations, and stress is more likely to lead to depression in girls than in boys. For boys, however, specific events, such as changing schools or getting poor grades, appear to be the major sources of stress.

A report issued in October 2006 by the American Academy of Pediatrics recommends more unstructured play time for children. The report notes that today’s overscheduled, hurried lifestyle that many children experience is a source of stress and anxiety in some children.

In a 1999 study of 46,000 workers, health care costs were 147% higher in workers who were stressed or depressed than in others who were not. Furthermore, according to one survey, 40% of American workers describe their jobs as very stressful, making job-related stress an important and preventable health hazard.

Several studies are now suggesting that job-related stress is as great a threat to health as smoking or not exercising. Stress impairs concentration, causes sleeplessness, and increases the risk for illness, back problems, accidents, and lost time from work. Work stress can lead to harassment or even violence while on the job. At its most extreme, chronic stress places a burden on the heart and circulation that in some cases may be fatal. The Japanese even have a word for sudden death due to overwork, karoushi.

Not all work stress is harmful. However, studies suggest the following job-related stressors may increase people's -- particularly men's -- health risks:

Having no say in decisions that affect one's responsibilities
Unrelenting and unreasonable performance demands
Lack of effective communication and conflict-resolution methods among workers and employers
Lack of job security
Night-shift work, long hours, or both
Too much time spent away from home and family
Wages not matching levels of responsibility

Reducing Stress on the Job. Many institutions within the current culture, while paying lip service to stress reduction, put intense pressure on individuals to behave in ways that increase tension. Yet, there are numerous effective management tools and techniques available to reduce stress. Furthermore, treatment for work-related stress has proven benefits for both the employee and employer. In one study, at the end of 2 years, a company that instituted a stress management program saved nearly $150,000 in workers compensations costs (the cost of the program was only $6,000). Other studies have reported specific health benefits resulting from workplace stress-management programs. In one of the studies, workers with hypertension experienced reduced blood pressure after even a brief (16-hour) program that helped them manage stress behaviorally.

In general, however, few workplaces offer stress management programs, and it is usually up to the employee to find their own ways to reduce stress. Here are some suggestions:

Seek out someone in the Human Resources department or a sympathetic manager and communicate concerns about job stress. Work with them in a non-confrontational way to improve working conditions, letting them know that productivity can be improved if some of the pressure is off.
Establish or reinforce a network of friends at work and at home.
Restructure priorities and eliminate unnecessary tasks.
Learn to focus on positive outcomes.
If the job is unendurable, plan and execute a career change. Send out resumes or work on transfers within the company.
If this isn't possible, be sure to schedule daily pleasant activities and physical exercise during free time.

It may be helpful to keep in mind that bosses are also victimized by the same stressful conditions they are imposing. For example, in one study of male managers in three Swedish companies, those who worked in a bureaucracy had greater stress-related heart risks than those who worked in companies with social supports.

Caregivers of Family Members. Studies show that caregivers of physically or mentally disabled family members are at risk for chronic stress. One study reported that overall mortality rates were over 60% higher in caregivers who were under constant stress. Spouses caring for a disabled partner are particularly vulnerable to a range of stress-related health threats, including influenza, depression, heart disease, and even poorer survival rates. Caring for a spouse with even minor disabilities can induce severe stress.

Specific risk factors that put caregivers at higher risk for severe stress, or stress-related illnesses, include:

Caregiving wives: Some studies suggest that wives experience significantly greater stress from caregiving than husbands do.
Having a low income.
Being African-American: African-American people tend to be in poorer physical health, and have lower incomes, than Caucasians. They therefore face greater stress as caregivers to their spouses than their white counterparts.
Living alone with the patient.
Helping a highly dependent patient.
Having a difficult relationship with the patient.

Intervention programs that are aimed at helping the caregiver approach the situation positively can reduce stress, and help the caregiver maintain a positive attitude. A 2002 program also demonstrated that moderate-intensity exercise was very helpful in reducing stress and improving sleep in caregivers.

Health Professional Caregivers. Caregiving among the health professionals is also a high risk factor for stress. One study, for example, found that registered nurses with low job control, high job demands, and low work-related social support experienced very dramatic health declines, both physically and emotionally.

People who are less emotionally stable or have high anxiety levels tend to experience specific events as more stressful than others. Some doctors describe an exaggerated negative response to stress as "catastrophizing" the event (turning it into a catastrophe). Nevertheless, a 2003 study of patients with anxiety disorder did not find any differences in actual physical response to stress (heart rate, blood pressure, release of stress hormones) compared to people without anxiety.

The lack of an established network of family and friends predisposes one to stress disorders and stress-related health problems, including heart disease and infections. A study, meanwhile, reported that older people who maintain active relationships with their adult children are buffered against the adverse health effects of chronic stress-inducing situations, such as low income or lower social class. Another study suggested this may be because people who live alone are unable to discuss negative feelings as a means to relieve their stress.

Studies of people who remain happy and healthy despite many life stresses conclude that most have very good networks of social support. One study indicated that support even from strangers reduced blood pressure surges in people undergoing a stressful event. Many studies suggest that having a pet helps reduce medical problems aggravated by stress, including heart disease and high blood pressure.

Lifestyle Changes

A healthy lifestyle is an essential companion to any stress-reduction program. General health and stress resistance can be enhanced by regular exercise, a diet rich in a variety of whole grains, vegetables, and fruits, and by avoiding excessive alcohol, caffeine, and tobacco.

Of interest, a 2003 study suggested that fish oil, which has been associated with a lower risk for heart disease and stroke, may blunt some of the harmful effects of mental stress on the heart.

In one study, high doses of vitamin C reduced stress levels and blood pressure. The doses given were higher than the recommended upper limit of 2,000 mg per day. High doses may cause headaches and diarrhea. Long-term use increases risk for kidney stones and has other adverse effects in specific individuals.

Exercise in combination with stress management techniques is extremely important for many reasons:

Exercise is an effective distraction from stressful events.
Exercise may directly blunt the harmful effects of stress on blood pressure and the heart (exercise protects the heart in any case).

Usually, a varied exercise regime is more interesting, and thus easier to stick to. Start slowly. Strenuous exercise in people who are not used to it can be very dangerous and any exercise program should be discussed with a physician. In addition, half of all people who begin a vigorous training regime drop out within a year. The key is to find activities that are exciting, challenging, and satisfying. The following are some suggestions:

Sign up for aerobics classes at a gym.
Brisk walking is an excellent aerobic exercise that is free and available to nearly anyone. Even short brisk walks can relieve bouts of stress.
Swimming is an ideal exercise for many stressed people, including pregnant women, individuals with musculoskeletal problems, and those who suffer exercise-induced asthma.
Yoga or Tai Chi can be very effective, combining many of the benefits of breathing, muscle relaxation, and meditation while toning and stretching the muscles. The benefits of yoga may be considerable. Numerous studies have found it beneficial for many conditions in which stress is an important factor, such as anxiety, headaches, high blood pressure, and asthma. It also elevates mood and improves concentration and the ability to focus.

As in other areas of stress management, making a plan and executing it successfully develops feelings of mastery and control, which are very beneficial in and of themselves. Start small. Just 10 minutes of exercise three times a week can build a good base for novices. Gradually build up the length of these every-other-day sessions to 30 minutes or more.

Cognitive-behavioral techniques (CBT) are among the most effective ways of reducing stress. A 2005 study found that CBT training can have a long-term impact one’s ability to cope with stress. In the study, participants received CBT training and were exposed to a stressful situation 4 months later. The participants who had received CBT training had significantly less stress-induced cortisol responses compared with individuals who had received no stress management training. This effect was observed in both men and women, although the CBT had a greater effect on men. CBT may be particularly helpful when the source of stress is chronic pain or a chronic disease. In fact, in a study of patients with HIV, CBT was more helpful than support groups for improving well-being and quality-of-life.

A typical CBT approach includes identifying sources of stress, restructuring priorities, changing one's response to stress, and finding methods for managing and reducing stress.

Identifying Sources of Stress. One key component in most CBT approaches is a diary that keeps an informal inventory of daily events and activities. While this exercise might itself seem stress producing (and yet one more chore), it need not be done in painstaking detail. A few words accompanying a time and date are usually enough to serve as reminders of significant events or activities.

The first step is to note activities that put a strain on energy and time, trigger anger or anxiety, or precipitate a negative physical response (such as a sour stomach or headache).

Also note positive experiences, such as those that are mentally or physically refreshing or produce a sense of accomplishment.

After a week or two, try to identify two or three events or activities that have been significantly upsetting or overwhelming.

Questioning the Sources of Stress. Individuals should then ask themselves the following questions:

Do these stressful activities meet my goals or someone else's?
Have I taken on tasks that I can reasonably accomplish?
Which tasks are under my control and which ones aren't?

Restructuring Priorities: Adding Stress Reducing Activities. The next step is to attempt to shift the balance from stress-producing to stress-reducing activities. Eliminating stress is rarely practical or feasible, but there are many ways to reduce its impact.

Consider as many relief options as possible. Examples include:

Listen to music. Music is an effective stress reducer in both healthy individuals and people with health problems. In one study, for example, students who listened to a well-known gentle classical piece of music during a stressful task had reduced feelings of anxiety, heart rate, and blood pressure.
Take long weekends or, ideally, vacations.
If the source of stress is in the home, plan times away, even if it is only an hour or two a week.
Replace unnecessary time-consuming chores with pleasurable or interesting activities.
Make time for recreation. This is as essential as paying bills or shopping for groceries.
Own a pet. In a study of people with high blood pressure, pet owners had much lower blood pressure increase in response to stress than non-owners. Note that owning a pet was beneficial only for people who like animals to begin with.

Discuss Feelings. The concept of communication and letting your feelings out has been so excessively promoted and parodied that it has nearly lost its value as good psychological advice. Nevertheless, feelings of anger or frustration that are not expressed in an acceptable way may lead to hostility, a sense of helplessness, and depression.

Expressing feelings does not mean venting frustration on waiters and subordinates, boring friends with emotional minutia, or wallowing in self-pity. In fact, because blood pressure may spike when certain chronically hostile individuals become angry, some therapists strongly advise that just talking, not simply venting anger, is the best approach, especially for these people.

The primary goal is to explain and assert one's needs to a trusted individual in as positive a way as possible. Direct communication may not even be necessary. Writing in a journal, writing a poem, or composing a letter that is never mailed may be sufficient.

Expressing one's feelings solves only half of the communication puzzle. Learning to listen, empathize, and respond to others with understanding is just as important for maintaining the strong relationships necessary for emotional fulfillment and reduced stress.

Keep Perspective and Look for the Positive. Reversing negative ideas and learning to focus on positive outcomes helps reduce tension and achieve goals. The following steps, using an example of a person who is alarmed at the prospect of giving a speech, may be useful:

First, identify the worst possible outcomes (forgetting the speech, stumbling over words, humiliation, audience contempt).
Rate the likelihood of these bad outcomes happening (probably very low or that speaker wouldn't have been selected in the first place).
Envision a favorable result (a well-rounded, articulate presentation with rewarding applause).
Develop a specific plan to achieve the positive outcome (preparing in front of a mirror, using a video camera or tape recorder, relaxation exercises).
Try to recall previous situations that initially seemed negative but ended well.

Use Humor. Research has shown that humor is a very effective mechanism for coping with acute stress. Keeping a sense of humor during difficult situations is a common recommendation from stress management experts. Laughter not only releases the tension of pent-up feelings and helps keep perspective, but it appears to have actual physical effects that reduce stress hormone levels. It is not uncommon for people to recall laughing intensely even during tragic events, such as the death of a loved one, and to remember this laughter as helping them to endure the emotional pain.

Relaxation Methods. Since stress is here to stay, everyone needs to develop methods to promote the relaxation response, the natural unwinding of the stress response. Relaxation lowers blood pressure, respiration, and pulse rates, releases muscle tension, and eases emotional strains. This response is highly individualized, but there are certain approaches that seem to work.

Combinations are probably best. For example, in a study of children and adolescents with adjustment disorder and depression, a combination of yoga, a brief massage, and progressive muscle relaxation effectively reduced both feelings of anxiety and stress hormone levels. A 2005 study of organ transplant recipients showed that training in meditation and gentle yoga led to significant improvements in quality of sleep and lessened anxiety and depression.

No one should expect a total resolution of stress from these approaches, but if done regularly, these programs can be very effective.

Acupuncture. Some evidence suggests that acupuncture may also be helpful. It might even improve some physical factors associated with stress and health problems. For example, in a study of heart failure patients, acupuncture improved stress-related heart muscle activity, which could be an important benefit in these patients. However, acupuncture had no effect on stress-related blood pressure or heart rate.

Hypnosis. Hypnosis may also benefit some people with severe stress. In one study of patients with irritable bowel, stress reduction by hypnosis correlated with improvement in many bowel symptoms.


*Deep Breathing Exercises.* During stress, breathing becomes shallow and rapid. Taking a deep breath is an automatic and effective technique for winding down. Deep breathing exercises consciously intensify this natural physiologic reaction and can be very useful during a stressful situation, or for maintaining a relaxed state during the day.	Inhale through the nose slowly and deeply to the count of 10. Make sure that the stomach and abdomen expand, but the chest does not rise. Exhale through the nose, slowly and completely, also to the count of 10. To help quiet the mind, concentrate fully on breathing and counting through each cycle. Repeat five to 10 times, and make a habit of doing the exercise several times each day, even when not feeling stressed.
*Muscle Relaxation.* Muscle relaxation techniques, often combined with deep breathing, are simple to learn and very useful for getting to sleep. In the beginning it is useful to have a friend or partner check for tension by lifting an arm and dropping it. The arm should fall freely. Practice makes the exercise much more effective and produces relaxation much more rapidly. Small studies have reported beneficial effects on blood pressure in patients with high blood pressure who use this technique.	After lying down in a comfortable position without crossing the limbs, concentrate on each part of the body. Maintain a slow, deep breathing pattern throughout this exercise. Tense each muscle as tightly as possible for a count of five to 10, and then release it completely. Experience the muscle as totally relaxed and lead-heavy. Begin with the top of the head and progress downward to focus on all the muscles in the body. Be sure to include the forehead, ears, eyes, mouth, neck, shoulders, arms and hands, fingers, chest, belly, thighs, calves, and feet. Once the external review is complete, imagine tensing and releasing internal muscles.
*Meditation.* Meditation, used for many years in Eastern cultures, is now widely accepted in this country as a relaxation technique. The goal of all meditative procedures, both religious and therapeutic, is to quiet the mind (essentially, to relax thought). Small studies have suggested that regular meditation can benefit the heart and help reduce blood pressure. Better research is needed, however, to confirm such claims. Some recommend meditating for no longer than 20 minutes in the morning after awakening and then again in early evening before dinner. Even once a day is helpful. Note: Meditating before going to bed may cause some people to wake up in the middle of the night, alert and unable to return to sleep. New practitioners should understand that it can be difficult to quiet the mind, and should not be discouraged by lack of immediate results. Several techniques are available. A few are discussed here. The only potential risks from meditating are in people with psychosis, in whom meditating may trigger a psychotic event.	Mindfulness Meditation. Mindfulness is a common practice that focuses on breathing. It employs the basic technique used in other forms of meditation. Sit upright with the spine straight, either cross-legged or sitting on a firm chair with both feet on the floor, uncrossed. With the eyes closed or gently looking a few feet ahead, observe the exhalation of the breath. As the mind wanders, simply note it as a fact and returns to the "out" breath. It may be helpful to imagine your thoughts as clouds dissipating away. Transcendental Meditation (TM). TM uses a mantra (a word that has a specific chanting sound but no meaning). The person meditating repeats the word silently, letting thoughts come and go. In one study, TM was as effective as exercise in elevating mood. Mini-Meditation. The method involves heightening awareness of the immediate surrounding environment. Choose a routine activity when alone. For example: While washing dishes, concentrate on the feel of the water and dishes. Allow the mind to wander to any immediate sensory experience (sounds outside the window, smells from the stove, colors in the room). If the mind begins to think about the past or future, or fills with unformed thoughts or worries, redirect it gently back. This redirection of brain activity from your thoughts and worries to your senses disrupts the stress response and prompts relaxation. It also helps promote an emotional and sensual appreciation of simple pleasures already present in a person's life.
*Biofeedback.* Biofeedback is a technique that measures bodily functions, like breathing, heart rate, blood pressure, skin temperature, and muscle tension. By watching these measurements, you can learn how to alter these functions by relaxing or holding pleasant images in your mind.	During biofeedback, electric leads are taped to a subject's head. The person is encouraged to relax using methods such as those described above. Brain waves are measured and an audible signal is emitted when alpha waves are detected, a frequency which coincides with a state of deep relaxation. By repeating the process, subjects associate the sound with the relaxed state and learn to achieve relaxation by themselves.
*Massage Therapy.* A 2005 report that reviewed data from multiple studies showed that massage therapy decreases cortisol levels. Another 2005 study showed that massage from a stable romantic partner can reduce physiological responses to a subsequent stressful event. In the study, women who received instructed shoulder-neck-massage from their partners before being exposed to stress had lowered cortisol responses, and smaller heart rate increases after the stressful event. Interestingly, massage was more beneficial than receiving social support from the partner, indicating the power of physical touch in managing stress. Several massage therapies are available.	Many massage techniques are available, such as the following: Swedish massage is the standard massage technique. It uses long smooth strokes, and kneading and tapping of the muscles. Shiatsu applies intense pressure to the same points targeted in acupuncture. It can be painful, but people report deep relaxation afterward. Reflexology manipulates acupuncture points in the hands and feet.

Some people who experience chronic stress seek herbal or natural remedies. It should be strongly noted, however, that just as with standard drugs, so-called natural remedies can cause problems, sometimes serious ones.

Probiotics. Probiotics are helpful bacterial strains that by themselves may provide a barrier against harmful bacteria. They do so through various mechanisms, such as excreting certain acids (for example, lactate, acetate) that inhibit harmful bacteria. They may also compete with them for nutrients. Stress reduces levels of these bacteria. Research even suggests that probiotics may help maintain remission in patients with IBD. In one small study, people suffering from stress and exhaustion significantly reduced their stress symptoms and gastrointestinal complaints when they took a probiotic supplement for 6 months. The specific bacteria that might be beneficial, however, are not fully known. The most well-known probiotics are the lactobacilli strains, such as acidophilus, which is found in yogurt and other fermented milk products. Others, however, may prove to be more important, such as bifidobacteria and GG lactobacilli. Other probiotics include the lactobacilli rhamnosus, casel, plantarium, bulgaricus, and salivarius, and also Enterococcus faecium and Streptococcus thermophilus.

Aromatherapy. The smell of lavender has long been associated with a calming effect. In a Japanese study, 14 women who were put in a room with a lavender scent experienced reduced mental stress. Several aromatherapies are now used for relaxation. Use caution, however, as some of the exotic plant extracts in these formulas have been associated with a wide range of skin allergies.

Valerian. Valerian is an herb that has sedative qualities and may reduce stress and associated physical effects. This herb is on the FDA's list of generally safe products. Of note, however, the herb's effects could be dangerously increased if it is used with standard sedatives. Other interactions and long-term side effects are unknown. Side effects include vivid dreams. High doses of valerian can cause blurred vision, excitability, and changes in heart rhythm.

Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, however, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been numerous reported cases of serious and even lethal side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements.

Special Warning on Kava. Kava has been commonly used to reduce anxiety and stress. It is now highly associated with liver injury and even liver failure in a few cases. Experts now strongly warn against its use.

People seeking relief from stress should be wary of things that promise a quick cure, or plans that include the purchase of expensive treatments. These treatments may be useless and sometimes even dangerous.

Surgery

Kyphoplasty, a surgical technique used to treat spinal fractures, does not improve a person's back pain or quality of life, according to a review published in 2006 by a nonprofit health services research agency. Kyphoplasty should only be done if bed rest, medicines, and physical therapy do not relieve back pain.

Ultrasound

Therapeutic ultrasound uses sound waves to deliver gentle vibrations to an area of the body. Scientists in England are studying whether therapeutic ultrasound may help relieve pain and disability due to sciatica.

Acupuncture

Studies continue to show that acupuncture helps some patients with low back pain. Now, research published in the British Medical Journal online says the alternative treatment seems to be worth the price in the long run.

Stem Cells

Researchers in England have pioneered a new technique to grow new spinal tissue using stem cells. Stem cells are the building blocks of specific cells. Every cell in the human body starts (or "stems") from a stem cell. Researchers say a patient's stem cells may someday be used to grow new tissue that can replace damaged discs.

Back pain tied to brain changes

Chronic back pain appears to be linked to tiny structural changes in the brain. German researchers have found that persons with chronic back pain have more activity in the parts of the brain involved in pain processing and emotional responses. It is unclear if the brain changes came before the pain or if they occurred in response to the pain. The scientists presented their findings at the 2006 Radiological Society of North American annual meeting.

Introduction

Back pain is one of the most common reasons people visit their doctor. According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, 8 out of 10 people have some type of backache.

Back pain can be acute or chronic.

Acute pain develops suddenly and goes away within 6 weeks. Acute pain is the most common type of back pain.
Chronic pain can come on fast or slow, but it lasts longer than 3 months. Back pain can occur in any area of the back, but it is more common in the lower part, which supports most of the body’s weight.

The back is highly complex, and pain may result from damage or injury to any of various bones, nerves, muscles, ligaments, and other structures. Still, despite sophisticated techniques that provide detailed anatomical images of the spine and other tissues, the cause of most cases of back pain remain elusive.

Vertebrae. The spine is a column of small bones, or vertebrae, that support the entire upper body. The column is grouped into three sections.

The cervical (C) vertebrae are the seven spinal bones that support the neck.
The thoracic (T) vertebrae are the twelve spinal bones that connect to the rib cage.
The lumbar (L) vertebrae are the five lowest and largest bones of the spinal column. Most of the body's weight and stress falls on the lumbar vertebrae.

Below the lumbar region is the sacrum, a shield-shaped bony structure that connects with the pelvis at the sacroiliac joints.

At the end of the sacrum are two to four tiny, partially fused vertebrae known as the coccyx or "tail bone."

Click the icon to see an image of the sacrum.

Each vertebra is designated by using a letter and number, which allows the doctor to determine where it is in the spine.

The letter reflects the spinal region where the vertebra is located: C=cervical (neck region), T=thoracic (chest, or middle back, region), and L=lumbar (lower back).
The number signifies the vertebra's place within that spinal region. The numbers start with 1 at the top of a region and count up as the vertebrae descend within the region. For example, C4 is the fourth bone down in the cervical region and T8 is the eighth thoracic vertebrae.

The Disks. Vertebrae in the spinal column are separated from each other by small cushions of cartilage known as intervertebral disks. The disks have no blood supply of their own. They need to rely on nearby blood vessels to keep them nourished.

Click the icon to see an image of an intervertebral disk.

Each disk is 80% water and contains two structures.

Inside each disk is a jelly-like substance called the nucleus pulposus.
The nucleus pulposus is surrounded by a tough, fibrous ring called the annulus.

Click the icon to see an image of the nucleus pulposus.

Processes. Each vertebra in the spine has a number of bony projections called processes. The spinal and transverse processes attach to the muscles in the back and act like little levers, allowing the spine to twist or bend. The particular processes form the joints between the vertebrae themselves, meeting together and interlocking at the zygapophysial joints (more commonly known as facet or z joints ).

Spinal Canal. Each vertebra and its processes surround and protect an arch-shaped central opening. These arches, aligned to run down the spine, form the spinal canal, which encloses the spinal cord.

Spinal Cord. The spinal cord is the central trunk of nerves that connects the brain with the rest of the body. Each nerve root passes from the spinal column to other parts of the body through small openings bounded on one side by the disk and the other by the facets. When the spinal cord reaches the lumbar region, it splits into four bundled strands of nerve roots called the cauda equina (meaning horsetail in Latin).

Causes

In about 85% of back pain cases, the origin of the pain is unknown, and imaging studies usually fail to determine the cause. Disk herniation and disk degeneration due to aging are the most common causes of low back pain. Other problems can also cause this pain, however.

Over the years, the disk can wear away (degenerate), causing inflammation and irritation. This age-related condition is a major source of chronic low back pain.

A herniated disk, sometimes, but incorrectly, called a slipped disk, is widely held to be the most common cause of severe back pain and sciatica. A disk in the lumbar area becomes herniated when it ruptures or thins out and degenerates to the point that the gel within the disk (nucleus pulposus) pushes outward. The damaged disk can take many forms.

A bulge -- The gel has been pushed out slightly from the disk and is evenly distributed around the circumference.
Protrusion -- The gel has pushed out slightly and asymmetrically in different places.
Extrusion -- The gel balloons extensively into the area outside the vertebrae or breaks off from the disk.

There is some debate, however, about how pain develops from a herniated disk and how frequently it causes low back pain. Many people have disks that bulge or protrude and do not suffer back pain. Extrusion (which is less common than the other two conditions) is highly associated with back pain, since the gel is likely to extend out far enough to press against the nerve root, most often the sciatic nerve. Extrusion is very uncommon, however, while sciatic and low-back pain are very common. But there may be other causes of low back pain

Ordinarily, at the time of any injury, the immune system triggers key factors that are designed to promote healing. Evidence is now pointing to an abnormal and persistent immune response in the cells of the nucleus pulposus that may be responsible for nerve injury and pain in the lower back. In such cases, the nucleus pulposus in the herniated disk overproduces certain factors known as cytokines -- notably tumor necrosis factor (TNF) -- that, in high levels, cause inflammation and cell damage. Evidence now suggests that such cytokines cause a biochemical reaction in the regions surrounding the bulging or protruded nucleus pulposus, which results in pain.

Abnormalities in the Annular Ring. Research has also focused on tears in the annular ring -- the fibrous band that surrounds and protects the disk. The annular ring contains a dense nerve network and high levels of peptides that heighten perception of pain. Tears in the annular ring are a frequent finding in patients with degenerative disk disease. Some cases of chronic low back pain may be caused by inward growth of nerve fibers into the annular ring, which triggers pain within the intervertebral disk.

At some time, up to 40% of people have pain called sciatica. This condition occurs when the sciatic nerve is trapped or inflamed.

The Sciatic Nerve. The sciatic nerve has an extensive pathway.

It first branches from the nerve roots that descend off the lowest part of the spinal cord (in the lumbar and sacral areas). Each of the two branches of the sciatic nerve is about as wide as a thumb.
Each branch of the nerve threads through the pelvis and deep into either side of the buttocks.
The nerve branches then pass down each hip and along the back of each thigh to the foot.

Causes of Sciatica. A herniated disk pressing on the sciatic nerve is the most common cause of sciatica, although spinal stenosis or other vertebral abnormalities that press on the sciatic nerve can also cause pain.

The main nerve traveling down the leg is the sciatic nerve. Pain associated with the sciatic nerve usually originates when nerve roots in the spinal cord become compressed or damaged. Symptoms can include tingling, numbness, or pain that radiates to the buttocks, legs, and feet.

Symptoms of Sciatica

Pain due to sciatica can vary widely. It may feel like a mild tingling, dull ache, or a burning sensation. In some cases, the pain is severe enough to cause immobility.

The pain most often occurs on one side. Some people have sharp pain in one part of the leg or hip and numbness in other parts. The affected leg may feel weak.

The pain often starts slowly. Sciatica pain may get worse:

At night
After standing or sitting for long periods of time
When sneezing, coughing, or laughing
After bending backwards or walking more than 50 - 100 yards (particularly if it is caused by spinal stenosis)

Sciatica pain usually goes away within 6 weeks, unless there are serious underlying conditions. Pain that lasts longer than 30 days, or gets worse with sitting, coughing, sneezing, or straining may indicated a longer recovery.

Other than age-related degenerative disk disorders, injuries in the muscles and ligaments supporting the back are the major causes of low back pain. Of note, is the iliac crest pain syndrome (iliolumbar syndrome), in which there are tears in the ligaments that help support the pelvic bone.

Spinal stenosis is the narrowing of the spinal canal. This typically develops as a person ages and the disks become drier and start to shrink. At some point in this process, any disruption, such as a minor injury that results in disk inflammation, can cause impingement on the nerve root and trigger pain. Pain from spinal stenosis can occur in both legs, or it can be felt as sciatica. Spinal stenosis occurs mostly in the elderly with degenerative osteoarthritis, but it can sometimes be caused by other problems, including infection and birth defects.

Spondylosis is a condition in which the fourth or fifth lumbar vertebrae degenerate or develop small fractures. This condition affects 4 - 6% of the general population, and the rates may be higher in certain populations. As it progresses, the spine can become unstable and lead to spondylolisthesis, in which one vertebra slips forward over the other and causes sciatica. The condition most often occurs in older individuals with women having a higher risk than men. It is also a common cause of back pain from stress fractures in young athletes and can also be due to inherited problems, injury, or bone disease.

Some cases of sciatica pain may occur when a muscle located deep in the buttocks pinches the sciatic nerve. This muscle is called the piriformis. The resulting condition is called piriformis syndrome. Piriformis syndrome usually develops after an injury. In rare cases leg swelling, deep-vein blood clots, or both may occur. Piriformis syndrome is sometimes difficult to diagnose.

Ankylosing spondylitis is a chronic inflammation of the spine that may gradually result in a fusion of vertebrae. Symptoms include a slow development of back discomfort, with pain lasting for more than 3 months. The back is usually stiff in the morning; pain improves with exercise. In severe cases, the patient must continually stoop over. It can be quite mild, however, and it rarely affects a person's ability to work. It occurs mostly in young Caucasians in their mid-20s. The disease is more common in men, but about 30% of the cases are in women. Researchers believe that in most cases it is hereditary. About 20% of people with inflammatory bowel disease and about 20% of people with psoriasis develop a form of ankylosing spondylitis. There are few effective treatments for this potentially disabling disease, although etanercept (Enbrel) and infliximab (Remicade), anti-inflammatory agents known as TNF-blockers, are proving to be beneficial.

Any abnormality in joints, vertebrae, or nerve roots can cause back pain:

The facet (z-joints) joints can wear down. In such cases, pain occurs on arching the back or when walking.
In some cases a segment (consisting of two vertebrae and their common joint and disk) becomes unstable when its parts wear down.
Injury to nerve roots, notably deep root ganglia (nerve cells in the spine whose fibers extend from skin to muscle tissue), may be important in some cases. Some patients may have scar tissue that traps the nerve roots in the lower spine and causes sciatica.

Risk Factors

In most known cases, pain begins with an injury, after lifting a heavy object, or after making a sudden movement. Not all people have back pain after such events, however. In the majority of back pain cases, the causes are unknown.

Some evidence suggests that after episodes of back pain, some people may experience changes in brain structure and chemicals that produce an exaggerated response in nerve cells. In fact, a 2005 study suggested that chronic back pain actually shrinks the brain by as much as 11%. Such brain changes may cause a persistent perception of pain even though the actual injury has healed.

German researchers have found that chronic back pain appears to be linked to tiny structural changes in the brain. Using a specialized imaging method, they learned that persons with chronic back pain seemed to have a different, more complex structure to their brain and more activity in the areas involved in pain processing and emotional responses. It is unclear if the brain changes occurred before the pain or in response to the pain.

A number of conditions may make people more or less susceptible to low back pain.

Intervertebral disks begin deteriorating and growing thinner by age 30. One-third of adults over 20 show signs of herniated disks (although only 3% of these disks cause symptoms). As people continue to age and the disks lose moisture and shrink, the risk for spinal stenosis increases. The incidence of low back pain and sciatica increases in women at the time of menopause as they lose bone density. In older adults, osteoporosis and osteoarthritis are also common. However, the risk for low back pain does not mount steadily with ever-increasing age, which suggests that at a certain point, the conditions causing low back pain plateau.

Inherited Spinal Structure Abnormalities. Many people have a genetic susceptibility to low back pain, usually from inheriting spinal structural abnormalities.

Inherited Weakened Disks. Studies are finding that specific mutations of the COL9A gene may play a role in about 10% of sciatica cases. The gene is normally involved in producing collagen, the protein building block in all structural tissue in the body. When defective, it may cause the disk to be less able to resist compressive forces. One 2001 study found the defective gene was present in twice as many patients with disk problems as in patients without back pain.

The likelihood of experiencing back pain increases as children age. Some studies suggest that pain is more common among girls than boys. A common cause of temporary back pain is carrying backpacks that are too heavy for children. Backpacks should not weigh more than 20% of the child's body weight. They should weigh even less for very young children. Emotional or behavioral problems may also contribute to back pain in children.

Jobs that involve lifting, bending, and twisting into awkward positions, as well as those that cause whole-body vibration (usually due to long-distance truck driving), place workers at particular risk for low back pain. The longer a person continues such a job, the higher the risk. Some workers wear back support belts, but evidence strongly suggests that they are useful only for people who are currently have low back pain. The belts offer little added support for the back and do not prevent back injuries. In one study, workers who wore the belt for prevention reported more back pain than the workers who did not wear them.

A number of companies are developing programs to protect against back injuries. Although studies are mixed on the outcome of company interventions, one analysis suggested that they do have a positive effect. Employers and workers should make every effort to create a safe working environment. Office workers should have chairs, desks, and equipment that support the back or help maintain good posture.

Infections. A number of common and uncommon infections are a cause of back pain. Chronic uterine or pelvic infections can cause low back pain in women. Osteomyelitis is infection in the spine, a rare cause of back pain. Other infections that cause back pain include Lyme disease, septic arthritis, bacterial endocarditis, Reiter syndrome, mycobacterial, fungal arthritis, and viral arthritis. Chlamydia pneumonia, an atypical organism that is a common cause of mild pneumonia in young adults, is now believed to cause widespread inflammation in the body's tissue, including blood vessels, and may be responsible for a number of chronic conditions, including heart disease. Some evidence further suggests it may cause inflammation in arteries of the lower spine and contribute to spinal stenosis.

Many medical conditions are associated with back pain.

Osteoporosis is a disease of the skeleton in which the amount of calcium present in the bones slowly decreases to the point where the bones become fragile and prone to fracture. It usually does not cause pain unless the vertebrae collapse suddenly, in which case the pain is often severe. Studies indicate, however, that the incidence of low back pain and sciatica increase around the time of menopause, and very tiny fractures in the vertebrae caused by osteoporosis may be an undetected cause of back pain in many elderly women.
Osteoarthritis occurs in joints where cartilage is damaged and then destroyed, usually as a result of aging. In reaction to this destruction, the bones associated with the joints develop abnormalities. When osteoarthritis affects the spine, it may damage the cartilage in the disks, the moving joints of the spine, or both. The nerves may become pinched, causing pain and in advanced cases, numbness and muscle weakness. The patient may also experience muscle spasms and diminished mobility.
Inflammatory disorders, such as Crohn's disease and rheumatoid arthritis, can produce inflammation in the spine (sacroiliitis), although the spine is less commonly affected than other locations.
Other conditions that can directly cause pain include fibromyalgia, Paget's disease, Parkinson's disease, abscesses, blood clots, and cancer.
Other medical conditions cause referred back pain, which occurs in conjunction with problems in organs unrelated to the spine (although usually located near it). Such conditions include ulcers, kidney disease (including kidney stones), ovarian cysts, and pancreatitis.

Osteoporosis is a condition characterized by progressive loss of bone density, thinning of bone tissue and increased vulnerability to fractures. Osteoporosis may result from disease, dietary or hormonal deficiency or advanced age. Regular exercise and vitamin and mineral supplements can reduce and even reverse loss of bone density.

It should be noted, however, that a number of medical conditions, such as lung and heart problems and chronic headaches, commonly occur with low back pain. A causal relationship among them, however, is uncertain.

Persistent low back pain in children is more likely to have a serious cause that requires treatment than back pain in adults. According to one small study, one third of children being treated at a hospital for back pain were found to have serious underlying problems.

Stress fractures (spondylolysis) in the spine are a common cause of back pain in young athletes. Sometimes a fracture may not show up for a week or two after an injury. Spondylolysis can cause spondylolisthesis, a condition in which the spine becomes unstable and the vertebrae slip over each other.

Hyperlordosis is an inborn exaggerated inward curve in the lumbar area. Scoliosis, an abnormal curvature of the spine in children, does not usually cause back pain.

Juvenile chronic arthropathy is an inherited form of arthritis. It can cause pain in the sacrum and hip joints of children and young people. It used to be grouped under juvenile rheumatoid arthritis, but is now defined as a separate problem.

Injuries, benign tumors such as osteoblastoma or neurofibroma and cancers, including leukemia, can also cause back pain in children.

Medications may trigger back pain. For example, anticoagulants can cause bleeding or an internal bruise. Long-term steroid use can cause infection or compression fractures.

Some research is suggesting that some people have motor control abnormalities in the deep muscles near the spine. Such lack of control causes instability in the spine that can lead to pain.

Pregnant women are prone to back pain due to a shifting of abdominal organs, the forward redistribution of body weight, and the loosening of ligaments in the pelvic area as the body prepares for delivery. Tall women are at higher risk than short women. Although some earlier research had suggested that the use of epidurals for pain relief during labor could lead to chronic back pain, studies in 2002 reported no increased risk.

Psychological factors are known to play a strong influential role in three phases of low back pain:

Some evidence suggests preexisting depression and the inability to cope may be more likely to predict the onset of pain than physical problems. For example, a British study reported that people who showed emotional distress at age 23 were nearly twice as likely to suffer from back pain 10 years later. A 2005 study found that a “passive” coping style (not wanting to confront problems) was strongly associated with the risk of developing disabling neck or low back pain.
The perception of pain. Social and psychological factors play a role in the severity of a person's perception of back pain. For example, one study compared truck drivers and bus drivers. Nearly all the truck drivers liked their work. Half of them reported low back pain but only 24% lost time at work. Bus drivers, on the other hand, reported much lower job satisfaction than truck drivers, and these workers with back pain had a significantly higher absentee rate than truck drivers in spite of less stress on their backs. Similarly, another study found that pilots, who generally reported "loving their jobs," reported far fewer back problems than their flight crews. And yet another study reported that low rank, low social support, and high stress in soldiers was associated with a higher risk for disabling back pain.
Chronic pain. Depression and a tendency to develop physical complaints in response to stress also increase the likelihood that acute back pain will become a chronic condition. The way a patient perceives and copes with pain at the beginning of an acute attack may actually condition the patient to either recover or develop a chronic condition. Those who over-respond to pain and fear for their long-term outlook tend to feel out of control and become discouraged, increasing their risk for long-term problems.

Studies also suggest that patients who reported prolonged emotional distress have less favorable outcomes after back surgeries. It should be strongly noted that the presence of psychological factors in no way diminishes the reality of the pain and its disabling effects. Recognizing it as a strong player in many cases of low back pain, however, can help determine the full range of treatment options.

Diagnosis

Because nearly all cases of low back pain clear up in a short time and are not due to serious problems, a medical history and a brief physical examination are almost always sufficient.

Still, with very severe or chronic back pain, it is important that any serious medical causes as well as cauda equina syndrome and progressive nerve damage be ruled out first. If the doctor suspects a serious underlying cause, the approach to determining the origin of back pain involves answering three questions:

Is some general medical disorder present that could be causing the pain?
Are there social or emotional factors that might be intensifying the pain?
Are the nerves in the spine involved in the pain (such as in sciatica)?

Such questions can usually be answered with a medical history and physical examination.

A patient should report any serious health problems and concerns during a medical and family history, especially those listed below.

Previous episodes of back pain
Any injuries or accidents involving the neck, back, or hips
History of cancer
Unexplained weight loss or chronic infection
The frequency, duration, and nature of the back pain
When the back pain occurs
What triggered the pain (such as lifting a heavy object)
Conditions that make the pain worse such as coughing
Any situation that relieves the pain
Urination of bowel movement problems
Other relevant symptoms such as morning stiffness, weakness, or numbness in the legs.

The main goal of a physician exam is to try and determine the source of the pain and to determine limits of movement.

Patients are asked to sit, stand, and walk in different ways (flat-footed, on the toes, and on their heels).
In some cases they are asked to walk on a treadmill to test for weakness in toe or heel walking (which may indicate stenosis).
Patients will be requested to bend forward, backward, and sideways and to twist.
Patients will be asked to lift their leg straight up while lying down. The doctor will also move the patient's legs in different positions and bend and straighten the knees. (Pain caused by sciatica can be intensified by lifting the affected leg straight in the air. It is usually sharp, localized, and accompanied by numbness or tingling. Pain caused by inflammation is duller and more generalized and not affected by lifting a straight leg.)
The doctor may measure the circumference of the calves and thighs to look for muscle deterioration.
To test nerve function and reflexes, doctors will tap the knees and ankles with a rubber hammer. The doctor may also touch parts of the body lightly with a pin, cotton swab, or feather to test for numbness and nerve sensitivity.

Because most patients with back pain are on the mend or completely recovered within 6 weeks, imaging techniques such as x-rays or scans are rarely recommended in the first month unless a tumor, fracture, infection, cauda equina syndrome, or progressive neurologic disease is suspected.

Patients who have the following symptoms or experienced certain events may need imaging studies.

Pain that lasts more than a month
Very severe or progressive pain, numbness
Muscle weakness
A previous accident or injury that might have affected the back
A history of cancer
Indications of an underlying disease such as fever or unexplained weight loss
Pain that occurs in patients over 65 years of age

If these conditions exist, usually an x-ray is used first. If results are inconclusive, either computed tomography (CT) or magnetic resonance imaging (MRI) may be performed. (Ultrasound is not useful.)

X-Rays. Although many patients with acute and uncomplicated low back pain believe that plain x-rays of the spinal column are important in a diagnosis, they are not very helpful in most patients except for reducing anxiety. If pain persists after 6 - 8 weeks, then x-rays are usually warranted. In such cases, x-rays may reveal signs of injury, infection, tumors, stenosis, or changes in the vertebrae that may be causing inflammation or compression on the nerve. There are many different types of x-rays for the spine.

A diskography is an x-ray of the disk. This procedure requires injections into disks suspected of being the source of pain and disks nearby. It can be painful and is generally only used for patients who are undergoing back surgery to identify the location of the injured disk.
An x-ray myelogram is an x-ray of the spine that requires a spinal injection of a special dye and the need to lie still for several hours to avoid a very painful headache. It has value only for select patients with pain on moving and standing. It has largely been replaced by CT and MRI scans.

CT stands for computerized tomography. In this procedure, a thin x-ray beam is rotated around the area of the body to be visualized. Using very complicated mathematical processes called algorithms the computer is able to generate a 3-D image of a section through the body. CT scans are very detailed and provide excellent information for the doctor.

Magnetic Resonance Imaging (MRI). Magnetic resonance imaging (MRI) can provide very well-defined images of soft tissue and bone. It is not painful, but some people may feel claustrophobic in scanners that are fully enclosed. MRIs can detect annular tears, or disk fragments, and non-spinal causes of back pain, including infection and cancer. However, MRIs are no more effective than x-rays in identifying arthritis, and they are more expensive. Some medical evidence suggests that relying on MRI images of disk abnormalities to determine treatment has resulted in many unnecessary surgeries. At least 40% of all adults have bulging or protruding vertebral disks, and most have no back pain. The degree of disk abnormalities revealed by MRIs often have very little to do with the severity of the pain or the need for surgery. Disk abnormalities in people who have back pain may simply be a coincidence rather than an indication for treatment.

Advanced imaging techniques should be used only when underlying infection, cancer, or nerve involvement is suspected.

Magnetic Resonance Neurography. This imaging exam looks at the nerves in the pelvic area. Researchers reporting in the Journal of Neurosurgery found that it helped reveal pinched nerves that can cause leg pain. The findings could lead to new ways to diagnose sciatica and piriformis syndrome.

Bone Scintigraphy and SPECT Imaging.In rare cases, doctors may use bone scintigraphy (bone scanning) to determine abnormalities in the bones. The technique may be useful for early detection of spinal fractures, cancer that has spread to the bone, or osteoarthritis. During this exam, a small amount of radioactive material is injected into a vein. It circulates through the body, and is absorbed by the bones. The bones can then be visualized using x-rays or single photon emission computed tomography (SPECT). A study in the February 2006 journal Radiology found that SPECT can help determine which patients would get low back pain relief from spinal injections. Forty-seven patients were randomly divided into two groups: One group received SPECT before they were scheduled for an injection, the other group did not. Those who showed spinal problems on the SPECT images received an injection in the area of the abnormalities. Those who had a normal SPECT, as well as those who did not have the test at all, received injections in the area recommended by their referring physician. After a month, those who had targeted injections using the SPECT images had greater pain relieve than those who did not.

Electrodiagnostic tests that analyze the electric waveforms of nerves and muscles may be useful for detecting nerve abnormalities that may be causing back pain and identifying possible injuries. They are also useful to determine if any abnormal structural findings on an MRI or other imaging test have real significance as a cause of the back pain. It should be noted that any nerve injuries that affect these tests may not be present for 2 - 4 weeks after symptoms begin.

Nerve conduction studies and electromyography are the electrodiagnostic tests most commonly performed.

Nerve Conduction Studies. To perform nerve conduction studies, surface electrodes are attached to the skin. Small electric shocks are then applied to measure the speed of nerve conduction.

Electromyography. To perform electromyography, a fine, sterile, wire electrode is inserted briefly into a muscle and the electrical activity is displayed on a viewing screen. Electromyography can be quite painful, and some experts question, in fact, whether it adds any valuable diagnostic information. They suggest it be limited to unusual cases or when other tests indicate that the condition is aggressive and may increase the risk for rapid, significant injury.

Blood and urine samples may be used to test for infections, arthritis, or other conditions.

Injecting a drug that blocks pain into the nerves in the back helps locate the level in the spine where problems occur.

A procedure called a facet block is also useful in locating areas of specific damage.

Provocative diskometry is a test that uses an injection of saline solution into the suspected disk to reproduce the pain, which is then followed by injection of an anesthetic to dull the pain.

Medications

The most commonly prescribed medications for the treatment of back pain are nonsteroidal anti-inflammatory drugs (NSAIDs). These drugs block prostaglandins, the substances that dilate blood vessels and cause inflammation and pain. Evidence suggests that short-term use of NSAIDs brings effective relief in patients with acute back pain. The benefits for chronic back pain are less certain.

There are dozens of NSAIDs. The most common are the following:

Over-the-counter NSAIDs include aspirin, ibuprofen (Advil, Nuprin, Motrin IB, Rufen), naproxen (Aleve), ketoprofen (Actron, Orudis KT).
Prescription NSAIDs include ibuprofen (Motrin), naproxen (Naprosyn, Anaprox), flurbiprofen (Ansaid), diclofenac (Voltaren), tolmetin (Tolectin), ketoprofen (Orudis, Oruvail), nabumetone (Relafen), dexibuprofen (Seractil), and indomethacin (Indocin).
Topical NSAIDs delivered in gels, creams, or patches do not appear to provide any long-term benefits in reducing arthritic pain.

Many experts now recommend that patients who take NSAIDs by mouth only do so for a short period of time. A 2004 review published in the British Medical Journal suggested that long-term use of NSAIDs does not actually reduce osteoarthritis pain and may increase patients’ risk of experiencing side effects. High dosages of NSAIDs can cause heart problems such as increased blood pressure, kidney problems, and stomach bleeding.

In April 2005, the FDA asked drug manufacturers of prescription NSAIDs to place an alert on their medicines warning people that the drugs have been linked to an increased risk for cardiovascular events and gastrointestinal bleeding. The FDA also requested manufacturers of OTC NSAIDs to revise their labels to include more specific language concerning potential cardiovascular and gastrointestinal risks. Aspirin does not contain such warning labels.

Long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) is the second most common cause of ulcers and the rate of NSAID-caused ulcers is increasing. Ulcers caused by nonsteroidal anti-inflammatory drugs (NSAIDs) are also more likely to bleed than those caused by the bacterium H. pylori.

Doctors cannot predict which patients taking these drugs will develop bleeding.

Among the groups at high risk for bleeding are elderly people, anyone with a history of ulcers of GI bleeding, patients with serious heart conditions, alcohol abusers, and those on certain medications, such anticoagulants ("blood thinners"), corticosteroids, or bisphosphonates (drugs used for osteoporosis).

Proton-pump inhibitors may help to prevent and heal ulcers caused by NSAIDs. Proton-pump inhibitors include omeprazole (Prilosec), esomeprazole (Nexium), and lansoprazole (Prevacid).

An ulcer is a crater-like lesion on the skin or mucous membrane that is caused by an inflammatory, infectious, or cancerous condition. To avoid irritating an ulcer, stop smoking and try to eliminate certain substances from your diet, including caffeine and alcohol. Prescription medicines are available to suppress the acid in the stomach that causes erosion of the stomach lining. Endoscopic therapy can be used to stop ulcer-related bleeding.

Coxibs block an inflammation-promoting enzyme called COX-2. This drug class was initially thought to work as well as NSAIDs, while causing less gastrointestinal distress. However, following numerous reports of cardiovascular events, gastrointestinal problems, and skin rashes, the FDA is currently re-evaluating the relative risks and benefits of this drug class. Rofecoxib (Vioxx) and valdecoxib (Bextra) have been withdrawn from the United States market. Celecoxib (Celebrex) is still available, but patients should ask their doctor if this drug is appropriate and safe for them.

Tramadol (Ultram) is a pain reliever that has been used as an alternative to opioids. It has opioid-like properties, but is not as addictive. (Dependence and abuse have been reported, however.) It can cause nausea, but does not cause the severe gastrointestinal problems that NSAIDs can. Some patients who take tramadol experience severe itching. A combination of tramadol and acetaminophen (Ultracet) is now available. It provides more rapid pain relief than tramadol alone.

Narcotics are pain-relieving and sleep-inducing drugs that act on the central nervous system. They are the most powerful medications available for the management of pain.

There are two types of narcotics:

Opiates are derived from natural opium such as morphine and codeine.
Opioids are synthetic drugs and include oxycodone (Percodan, Percocet, Oxycontin), hydrocodone (Vicodin), and oxymorphone (Numorphan).

Novel ways to deliver pain medicine have been developed. A skin patch containing an opioid called transdermal fentanyl (Duragesic) may relieve chronic back pain more effectively than oral opioids. For very severe pain, a small, patient-controlled pump called SynchroMed may be used. This device is implanted under the skin in the abdomen and delivers pulses of pain-relieving opioids to the spinal canal.

Common side effects of opioids include anxiety, constipation, nausea and vomiting, dizziness, drowsiness, paranoia, urinary retention, restlessness, and labored or slow breathing. Addiction is a risk, although less than is commonly believed when these medications are used for pain relief. In fact, when prescribed properly, use of opioids for chronic pain can be safer in some cases than on-going use of NSAIDs. Unfortunately, opioid abuse among young people is a major concern. Unless the pain is very severe, experts advise against routinely prescribing opioids.

Injections of different substances are sometimes used to treat low back pain caused by nerve impingement. The injection is usually an epidural, which is directed into the spaces between the outer membrane of the spine and the vertebrae. None of these substances cure the problem.

Corticosteroids. An injection of a corticosteroid (commonly called a steroid) is directed as close to the injured location as possible. Corticosteroids reduce inflammation. This approach may temporarily relieve sciatic pain until the body heals itself. Studies that measure the benefits of steroids on sciatica or low back pain are conflicting. There is some evidence that patients can experience rebound pain within a few months. Some experts have also raised concerns that even a single injection can cause serious and painful side effects, including meningitis and inflammation, although such risks are very low.
Hypertonic saline (salt water solution). Epidural injections of saline are being investigated for breaking up scar tissue. One 2001 study compared targeted injections of saline and steroids directed at the nerve root. Although steroid injections had more immediate benefits, both products offered improvement. By the third month, patients who had saline injections experienced less pain than the steroid group. A 2003 study found that epidural corticosteroid injections provided no greater benefit than saline injections for patients with sciatica.
Local anesthetics. Injections of anesthetics such as Xylocaine or bupivacaine may help some patients, although studies on their benefits are mixed.
Botulinum. Researchers are investigating whether injections of botulinum toxin (Botox) in the lower back can safely and effectively relieve pain. Very small amounts of Botox temporarily paralyzes muscle tissue. Botox is commonly used to smooth out wrinkles. Some studies have suggested that Botox may be very helpful in relieving chronic low back pain and sciatica caused by piriformis syndrome. In a 2001 study, the benefits of Botox injections for low back pain subsided within 6 months.

A 2002 review of studies concluded that antidepressants may lessen pain severity in some patients, although they had little effect on daily functioning. Antidepressants called tricyclics can be effective painkillers in non-depressed people with chronic back pain. Such antidepressants include amitriptyline (Elavil, Endep), desipramine (Norpramin), doxepin (Sinequan), imipramine (Tofranil), amoxapine (Asendin), nortriptyline (Pamelor, Aventyl), and maprotiline (Ludiomil). It should be noted that tricyclics can have severe side effects. Nonetheless, experts believe there is a useful role for these drugs that warrants further investigation.

A combination of nonsteroidal anti-inflammatory drugs (NSAIDs) and muscle relaxants such as cyclobenzaprine (Flexeril), diazepam (Valium), carisoprodol (Soma), or methocarbamol (Robaxin) are sometimes used for patients with acute low back pain. Medical evidence has found that they can help relieve non-specific low back pain, but some experts have warned that these drugs should be used cautiously, since they target the brain, not the muscles. Patients who take muscle relaxants may experience a number of central nervous system side effects such as drowsiness. The muscle relaxant Soma can be addictive and does little more than produce sleep.

Tumor-Necrosis Factor (TNF) Modifiers. TNF modifiers block the action of tumor necrosis factor, a protein involved in inflammatory response. Because of their anti-inflammatory properties, TNF modifier drugs are being investigated for the treatment of the nerve dysfunction and pain that occurs in sciatica. Some small studies indicate that infliximab (Remicade) may help reduce sciatica pain. Early studies suggest that another TNF modifier, etanercept (Enbrel), may be useful for treating sciatica and back pain. TNF modifiers are powerful drugs that can cause severe side effects.

Lidocaine Patch. A skin patch containing lidocaine, a local anesthetic, has been used specifically for herpes zoster pain. Early studies suggest that this patch, called Lidoderm, may provide significant relief for people who suffer from low back pain with very few adverse effects, even with continuous use of four patches a day. If further studies support its benefits, the patch could prove to be an important treatment

NO-NSAIDs. NO-NSAIDs are drugs that combine NSAIDs and nitric oxide (NO), a substance that enhances blood flow to the stomach and increases levels of protective mucus and bicarbonate. These agents show particular promise in providing pain relief and reducing the risk for GI problems.

Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been a number of reported cases of serious and even lethal side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements.

Most herbal remedies used for back pain have both pain-relief and anti-inflammatory effects. Popular herbs for back pain relief include:

White willow bark (Salix alba) contains salicylates, the same chemicals found in aspirin.
Bromelain is an enzyme found in pineapple.
Boswellia (Boswellia serrata) is an herb commonly used in Indian Ayurvedic medicine.
Devil’s claw (Harpagophytum procumbens) is an African herb sometimes used to relieve arthritic pain.

White willow bark, bromelain, and Boswellia have blood-thinning properties and can interfere with anticoagulant medications such as warfarin (Coumadin).

Complementary and Alternative Medicine

A number of complementary and alternative treatments are used to relieve back pain. Complementary means it is used together with conventional medicine. Alternative means it is done in place of conventional medicine.

Acupuncture is now a common alternative treatment for certain kinds of pain. It involves inserting small needles or exerting pressure on certain "energy" points in the body. When the pins have been placed successfully, the patient is supposed to experience a sensation that brings a feeling of fullness, numbness, tingling, and warmth with some soreness around the acupuncture point. Unfortunately, rigorous studies of acupuncture are difficult to perform, and most evidence on its benefits is weak. In any case, it may be specifically helpful for certain patients with back pain, such as pregnant women, who must avoid medications. Anyone who undergoes acupuncture should be sure it is performed in a reputable location by experienced practitioners who use sterilized equipment.

A number of well-conducted studies have supported the benefits of massage therapy for patients with chronic or acute back pain, especially when it is combined with exercise and patient education. In fact, one analysis in 2003 suggested it may reduce the costs of care. However, it is usually not covered by insurance.

According to a 2001 review of studies, only intensive programs that include both psychological and physical rehabilitation therapies were successful in reducing chronic low back pain and improving function. A number of effective approaches to low back pain -- collectively called mind-body techniques -- employ psychological, behavioral, or physical methods to promote relaxation and reduce stress. Although many may be helpful, evidence is lacking on the specific approaches that would be most successful and which patients would most likely benefit.

Stress Reduction. Stress reducing techniques, including relaxation methods and meditation, may be helpful. One study, for example, reported that meditation was beneficial in reducing pain and improving mood among chronic pain sufferers who had not responded to traditional care. Another found that after 3 weeks, patients who were in pain after back surgery had less discomfort and slept better after practicing relaxation imagery techniques while listening to music for 25 minutes a day.

Cognitive-Behavioral Therapy. Studies report that a course of cognitive-behavioral therapy helps reduce chronic back pain or at least enhances the patient's ability to deal with it. The primary goal of this form of therapy in such cases is to change the distorted perceptions that patients have of themselves and their approach to pain. Using specific tasks and self-observation, patients gradually shift their fixed ideas that they are helpless against the pain that dominates their lives to the perception that pain is only one negative and, to a degree, a manageable experience among many positive ones. In one study, therapists also taught relaxation techniques and methods to improve posture. The sessions lasted for 2.5 hours each week for 12 weeks. More research is needed.

Patient Education and Support Groups. A 2002 study reported that patients with chronic low back pain who participated in an expert-moderated e-mail support and discussion group had less pain and disability after 12 months. An Australian massive public-health campaign that educated patients and doctors about the importance of staying active and dispelled fears about long-term impairment from back pain dramatically reduced disability and worker compensation claims.

Spinal Manipulation for Uncomplicated Acute Low Back Pain. Spinal manipulation may be useful for acute back pain that persists beyond 2 - 3 weeks. There are a number of variations, but one example of a spinal manipulation technique is the following:

The patient first lies on their side.
The practitioner grasps the exposed shoulder and either the hip or knee and then presses the upper and lower portions of the body in opposite directions, so that the torso rotates.
The shifting vertebrae make a cracking or popping sound, indicating that they have exceeded the normal range of motion.
Often this results in a greater sense of ease and mobility. (The effect, however, may be temporary.)

Whether on-going manipulations relieve pain better that just one visit is a subject of debate. Some patients consider spinal manipulation to be highly effective for chronic low back pain. A major 2003 analysis, however, reported that current evidence did not support the benefits of spinal manipulation over general medical care or physical therapy for either acute or chronic back pain. [It was better than sham (fake) therapy, however.]

Spinal manipulations are typically performed by chiropractors, but osteopathic doctors also perform them.

One in three people with low back pain seek treatment from a chiropractor. Chiropractic was founded in the U.S. in the late 1800s. The specific goal of chiropractors is to perform spinal manipulations to improve nerve transmission. Many studies have now confirmed that patients feel more satisfied with their chiropractic care than with treatment from general practitioners.
Osteopathy was also founded in the 1800s. Its core approach to healing also involves physical manipulation. Osteopathy manipulates the bones, muscles, and tendons to optimize blood circulation. The general direction of osteopathy over the years has widened to employ a broader range of treatments that now approach those of standard medicine. One 1999 study reported that osteopathy was as effective as medical treatment in relieving low back pain and patients required far less medication and physical therapy. Osteopathic treatment was also far less expensive than traditional back pain treatments.

Both chiropractors and osteopaths offer verbal assurance and a precise treatment regimen. The direct physical connection through spinal manipulation reinforces the patient-practitioner relationship. The emotional effects of such connections may be as important for healing as the treatments themselves.

Mild and temporary side effects from spinal manipulation are common. The potential for serious adverse effects from low back manipulations is low. It should be strongly noted, however, that serious complications (including stroke or spinal cord or neck injury) have been reported with manipulations of the neck. Although little research has been done on such complications, an English survey indicated that they are more frequent than commonly thought.

Some chiropractors may take a lot of x-rays, particularly those of the full spine, which may have long-term harmful consequences. Patients should also be aware that some chiropractors use alternative treatments that have not been proven or rigorously studied. All patients should require objective evidence on the benefits of their treatments.

Vertebral Axial Decompression. Vertebral axial decompression (VAX-D) may reduce pain and improve function in patients with chronic low back pain, including sciatic pain that radiates down the leg. The patient lies face down on a special table, clutching hand grips and wearing a pelvic harness. The traction-like action alternately decompresses and relaxes the spine over 1-minute intervals. Each session lasts about 30 minutes. Ten to 20 sessions on successive days are often required. The procedure is thought to alleviate pain and enhance healing by relieving pressure within the disks, promoting the in-flow of oxygen, fluids, and nutrients to the spinal column. Some evidence supports its benefits, with reported success rates of around 70%. Because it is considered experimental, it is not yet covered by most insurers. More studies are needed to confirm its possible benefits.

Percutaneous Neuromodulation Therapy. A technique called percutaneous neuromodulation therapy (PNT) uses a small device delivers electrical stimulation to deep tissues and nerve pathways near the spine. It has shown some initial promise for relief of chronic back pain and may also improve mobility and sleep. Treatment sessions are conducted in the doctor's office and last about 30 minutes. A correct pattern of stimulation appears to be important for optimal relief and needs to be determined.

Electric Nerve Stimulation. Transcutaneous electric nerve stimulation (TENS) uses low-level electrical pulses to suppress back pain. A variant, percutaneous electrical nerve stimulation (PENS), applies these pulses through a small needle to acupuncture points. The standard procedure is to give 80 - 100 pulses per second for 45 minutes three times a day. The patients are barely aware of the sensation. Although a 2002 analysis of trials could find no direct evidence of benefit, small studies have reported some relief for chronic low back pain from either TENS or PENS. It is not known if these effects are long lasting. Neither approach is helpful for relief of acute low back pain in most patients.

Muscle Stimulation. Two investigative procedures called automated or electrical twitch obtaining intramuscular stimulation (ATOIMS or ETOIMS) are showing promise. ATOIMS uses an automated mechanical device that vibrates the muscle using a tiny pin. (The sensation is described as similar to a mosquito bite.) ETOIMS uses an extremely mild electrical current. They can also be used together. Both approaches cause the muscles to twitch and then relax then the process is stopped. Discomfort is minimal. Small studies are reporting some help in relieving a number of condition the cause chronic pain, including low back pain.

Therapeutic ultrasound. Therapeutic ultrasound involves placing a small wand or probe directly onto the skin. The wand gives off sound waves, which gently vibration the area. Scientists in England are studying whether therapeutic ultrasound may help relieve pain and disability due to sciatica.

Intradiscal Electrothermal Treatment (IDET). Intradiscal electrothermal treatment (IDET) uses electricity to heat a painful disk. Heat is applied for about 15 minutes. Pain may temporarily feel worse, but after healing, the disk shrinks and becomes desensitized to pain. However, healing takes several weeks. The surgery may not work in obese patients.

Some studies have reported positive benefits to IDET; others say it does not significantly reduce pain. A randomized, blinded study published in the November 2005 journal Spine found that IDET was no better than a sham (fake) procedure in relieving chronic back pain due to disk disease. For the study, patients were randomly selected to receive either IDET or a sham procedure. After 6 months, there was no difference in pain symptoms between the two groups.

Exercise and Physical Therapy

Incorrect movements or long-term high-impact exercise is often a cause of back pain in the first place. People vulnerable to back pain should avoid activities that put undue stress on the lower back or require sudden twisting movements, such as football, golf, ballet, and weight lifting.

Exercise does not help acute back pain. In fact, overexertion may cause further harm.

An incremental aerobic exercise program (such as walking, stationary biking, swimming) may begin within 2 weeks of symptoms. Jogging is usually not recommended, at least not until the pain is gone and muscles are stronger.

Patients should avoid exercises that put the lower back under pressure until the back muscles are well toned. Such exercises include leg lifts done in a facedown position, straight leg sit-ups, and leg curls using exercise equipment.

In all cases, patients should never force themselves to exercise if, by doing so, the pain increases.

Exercise plays a very beneficial role in chronic back pain. Repetition is the key to increasing flexibility, building endurance, and strengthening the specific muscles needed to support and neutralize the spine. Exercise should be considered as part of a broader program to return to normal home, work, and social activities. In this way, the positive benefits of exercise not only affect strength and flexibility but they also alter and improve patients' attitudes toward their disability and pain. Exercise may also be effective when combined with a psychological and motivational program, such as cognitive-behavioral therapy.

There are different types of back pain exercises. A 2005 review in the Annals of Internal Medicine found that stretching exercises worked best for reducing pain, while strengthening exercises were best for improving function.

Back pain exercises include:

Low Impact Aerobic Exercises. Low-impact aerobic exercises, such as swimming, bicycling, and walking, can strengthen muscles in the abdomen and back without over-straining the back. Programs that use strengthening exercises while swimming may be a particularly beneficial approach for many patients with back pain. Medical research has shown that pregnant women who engaged in a water gymnastics program have less back pain and are able to continue working longer.
Lumbar Extension Strength Training. Exercises called lumbar extension strength training are proving to be effective. Generally, these exercises attempt to strengthen the abdomen, improve lower back mobility, strength, and endurance, and enhance flexibility in the hip and hamstring muscles and tendons at the back of the thigh.
Yoga, Tai Chi, Chi Kung. Practices originating in Asia that combine low-impact physical movements and meditation may be very helpful. They are designed to achieve a physical and mental balance and can be very helpful in preventing recurrences of low back pain.
Pilates, an exercise practice that uses yoga principles, may be specifically helpful.
Flexibility Exercises. Flexibility exercises may help reduce pain. A stretching program may work best when combined with strengthening exercises.
Retraining Deep Muscles. Some studies suggest a link between low back pain and impaired motor control of deep muscles of the back and trunk. According to these studies, contraction exercises specifically designed to retrain these muscles may be effective for patients with both acute and chronic pain.

Perform the following exercises at least three times a week:

Partial Sit-ups. Partial sit-ups or crunches strengthen the abdominal muscles.

Keep the knees bent and the lower back flat on the floor while raising the shoulders up 3- 6 inches.
Exhale on the way up and inhale on the way down.
Perform this exercise slowly 8 - 10 times with the arms across the chest.

Pelvic Tilt. The pelvic tilt alleviates tight or fatigued lower back muscles.

Lie on the back with the knees bent and feet flat on the floor.
Tighten the buttocks and abdomen so that they tip up slightly.
Press the lower back to the floor, hold for one second, and then relax.
Be sure to breathe evenly.

Over time increase this exercise until it is held for 5 seconds. Then, extend the legs a little more so that the feet are further away from the body and try it again.

Stretching Lower-Back Muscles. The following are three exercises for stretching the lower back:

Lie on the back with knees bent and legs together. Keeping arms at the sides, slowly roll the knees over to one side until totally relaxed. Hold this position for about 20 seconds (while breathing evenly) and then repeat on the other side.
Lying on the back, hold one knee and pull it gently toward the chest. Hold for 20 seconds. Repeat with the other knee.
While supported on hands and knees, lift and straighten right hand and left leg at the same time. Hold for 3 seconds while tightening the abdominal muscles. The back should be straight. Alternate with the other arm and leg and repeat on each side 8 - 20 times.

Note: No one with low back pain should perform exercises that require bending over right after getting up in the morning. At that time, the disks are more fluid-filled and more vulnerable to pressure from this movement.

Physical therapy with a trained professional may be useful if pain has not improved within the first 3 weeks. It is, in fact, important for any person who has chronic low back pain to have an exercise program guided by professionals who understand the limitations and special needs of back pain and who can address individual health conditions. One study indicated that patients who planned their own exercise did worse than those in physical therapy or doctor-directed programs.

Physical therapy typically includes the following:

The first stage involves patient education and training the patient in correct movement. Sometimes heat or electro-therapies (such as therapeutic ultrasound or low-energy lasers) are used, although their benefits are unproven.
If back pain persists beyond 5 weeks, physical therapy is used for rehabilitation. It uses exercises to help the patient keep the spine in neutral positions during all daily activities.

Surgery

Diskectomy is the surgical removal of the diseased disk. The procedure relieves pressure on the spine. It has been performed for 40 years with increasingly less invasive techniques being developed over time. However, few studies have been conducted to determine its real effectiveness. In appropriate candidates it provides faster immediate relief than medical treatment, but long-term benefits (over 5 years) are uncertain. A number of minimally invasive variations are now available.

When the soft, gelatinous central portion of an intervertebral disk is forced through a weakened part of a disk, it is called a slipped disk. Most slipped disks (herniated disks) take place in the lumbar area of the spine. Slipped disks are one of the most common causes of lower back pain. The mainstay of treatment is an initial period of rest with pain and anti-inflammatory medications followed by physical therapy. If pain and symptoms persist, surgery to remove the herniated portion of the intervertebral disk may be needed.

Microdiskectomy. Microdiskectomy is the current standard procedure. It is performed through a small incision (1 to 1-1/2 inch). The back muscles are lifted and moved away from the spine. After identifying and moving the nerve root, the surgeon removes the injured disk tissue under it. The procedure does not change any of the structural supports of the spine, including joints, ligaments, and muscles.

Other less invasive procedures that are available including the following:

Endoscopic Diskectomy. Endoscopy employs a catheter (a thin tube) that contains tiny cameras and surgical instruments that are inserted through small incisions. Various endoscopic approaches are proving to be useful for back surgery.
Percutaneous Diskectomy. Percutaneous diskectomy (PAD). This approach uses a tube with a device at the tip that cuts away some of the nucleus pulposus and a vacuum that then sucks this gelatinous matter out.
Laser Diskectomy. A number of investigative surgical procedures employ lasers. For example, endoscopic laser foraminoplasty (ELF) uses lasers to locate the likely source of pain and remove diseased tissue. The incision requires little more than a Band-Aid and complications are minimal. Long-term benefits are unknown, however.

It is not clear yet if any of these less-invasive procedures are any more effective than the standard microdiskectomy.

Complications and Outlook. Many patients still have back pain after diskectomy that delays discharge from the hospital. Narcotics are usually needed. Adding an injected NSAID may speed resolution of pain.

Scar tissue is a significant problem, since it can cause persistent low back pain afterward. Anti-scarring agents or certain devices may help reduce surgical scars and thereby postoperative pain. Other complications of spinal surgery can include nerve and muscle damage, infection, and the need for reoperation.

Patients now often remain in bed only 3 - 4 days after disk surgery. It may take 4 - 6 weeks for full recovery, however. Gentle exercise may be recommended at first. Starting intensive exercise 4 - 6 weeks after a first-time disk surgery appears to be very helpful for speeding up recovery.

Operations that remove a vertebra (laminectomy) or shave off part of one (laminotomy) may be used in certain cases of spinal stenosis or spondylolisthesis to decompress the nerve. They may also be used to remove benign tumors on the spine.

Although either procedure often brings immediate relief from pain, a 1999 statistical study suggested that it is inappropriately performed in 60% or more of sciatica cases. There are small risks to the operation, and it is not always successful. Some recurrence of back pain and sciatica occurs in half to two-thirds of postoperative patients. Minimally invasive variations are under investigation.

In cases where abnormal vertebrae position or movement is responsible for severe and chronic back pain, such as spinal stenosis or spondylolisthesis, surgeons may fuse vertebrae together. Fusion uses a bone graft or some other device to join the vertebrae together. In a 2001 study of patients with severe long-term back pain, 33% of patients who had spinal fusion had less back pain after 2 years, compared to 7% who received conservative treatment with physical therapy. Pain improved most in the 6 months following surgery. However, a 2005 clinical trial found that spinal fusion surgery worked no better than intensive rehabilitation in reducing disability. The intensive rehabilitation program included both physical and cognitive-behavioral therapy.

Many spinal fusion surgeries use a tiny hollow metal cage, which is implanted into the disk space. Bone is then removed from the patient's hip and packed inside the cage. Over time the bone grows through the holes and around the device, fusing the vertebrae. Alternatively, rather than performing a bone graft, the cage is filled with a sponge-like material containing a genetically-engineered protein called InFuse (rhBMP-2) that promotes bone to grow.

A number of video-assisted techniques have been developed. The new techniques are less invasive than standard "open" surgical approaches, which uses wide incisions. To date, however, the newer procedures have higher complication rates than the open approaches and some medical centers have abandoned them.

Percutaneous Vertebroplasty. Percutaneous vertebroplasty involves the injection of a cement-like bone substitute into vertebrae with compression fractures. It is done under endoscopic and x-ray guidance. The technique is proving useful for stabilizing the spine and relieving pain in patients with spinal compression fractures due to osteoporosis or cancer. A Mayo Clinic study found that patients who have the procedure have less back pain during rest and activity. A survey of records from more than 100 vertebroplasty patients revealed that most patients are more functional than before the procedure, and the benefits lasted for up to a year. Warning: The FDA has warned consumers that polymethylmethacrylate bone cement, used during vertebroplasty, could leak. Such leakage could cause damage to soft tissues and nerves. It is extremely important that the patient is sure that the health care provider has had significant experience performing the vertebroplasty procedure.

Percutaneous kyphoplasty. The health care provider injects bone cement into the space surrounding a fractured vertebra. (Vertebroplasty injects the cement directly into the vertebra.) Kyphoplasty is used to stabilize the spine and return spinal cord height to as normal as possible. However, a review published in 2006 by a nonprofit health services research agency found that the technique does not improve a person's back pain or quality of life. Kyphoplasty should only be done if bed rest, medicines, and physical therapy do not relieve back pain. Those with severe fractures or spinal infections should not have kyphoplasty.

Artificial Disk Replacement. Total disk replacement is an investigative procedure for some patients with severely damaged disks. The technique implants artificial disks (ProDisc, Link, SB Charite) consisting of two metal plates and a soft core. The surgery can be performed using a minimally invasive laparoscopic procedure, which is performed through tiny cuts using miniature tools and viewing devices. A study in 2003 was the first to suggest that it may eventually achieve results that are comparable to standard surgeries for disk herniation. An artificial cushioning device called the prosthetic disk nucleus (PDN) replaces only the inner gel-like core (nucleus pulposus) within the intervertebral space, rather than the entire disk. It is showing promise in early studies.

Nerve Blocks. A number of surgical techniques are available for relieving pain by impairing nerves that are causing pain due to impingement. Medical research has shown that 60% of the patients who received electrical stimulation to block the nerves reported at least 90% relief of pain after a year; 87% reported at least 60% relief.

Other Treatments

Radiofrequency Nerve Destruction. Radiofrequencies are being used to destroy nerves involved in the facet joints (or z-joints), which connect the vertebrae. Evidence is still weak on its benefits. A 2003 analysis suggested that it may be beneficial, however, for relief of neck pain and possibly for low back pain caused by problems in the facets joints. Serious infections have been reported.

Stem cell treatments. Researchers in England have pioneered a new technique to grow new spinal tissue using the patient's own stem cells. Stem cells are the building blocks of specific cells. Every cell in the human body starts (or "stems") from a stem cell. The new tissue will replace damaged spinal tissue and may relieve low back pain. Researchers expect the treatment to enter pre-clinical trials in about 1 year.

Specific Treatment for Acute Low Back Pain

Patients with short-term acute low back pain usually have the best results with the least aggressive treatments. The general approach is as follows:

Patients with no serious underlying cause should stay as active as possible within the limits of the back pain. (Bed rest is not recommended.)
Physical therapy or spinal manipulations may be helpful if pain continues for more than 2 - 3 weeks.
The patient should seek a specialist if pain continues for more than 1 month. (Some patients may need to see a specialist sooner if there is an underlying disorder, nerve damage, or injury.) Back pain due to medical conditions such as arthritis, osteoporosis, or pregnancy either goes away when the underlying condition disappears or is treated.

Home Care Tips for Relieving Pain

Resume normal activity as soon as possible. Bed rest is no longer recommended and may delay recovery. Activities should be done without strain or stretching.
Avoid intense exercise and physical activity, particularly heavy lifting and trunk twisting if there is acute back pain.
Try an over-the-counter nonsteroidal anti-inflammatory such as aspirin or ibuprofen. These medicines often provide significant benefits.
Apply heat (104°) to the painful area. Heat may work better than ibuprofen or acetaminophen. One group of researchers found that people with low back pain who wear low-level heat wraps for 8 hours a day have significant less pain and disability.
Try alternating between hot and cold packs. Some doctors recommend changing from hot to cold every 3 minutes and repeating this sequence three times. Others believe ice packs should be applied first. This routine should be done two or three times during the day. (Note: Heat or cold treatments do not have much effect on sciatica.)
Supportive back belts, braces, or corsets may help some people temporarily, but these products can reduce muscle tone over time and should be used only briefly.
Get plenty of sleep. Healthy sleep plays a vital role in recovery. Avoid caffeine in the afternoon and evening, and unwind before bed by taking a warm bath or practicing relaxation techniques. It is often difficult to get a good night's sleep when suffering from back pain, particularly because the pain can intensify at night. Some people may need medicine to help manage nighttime pain or treat sleeplessness. Lying curled up in a fetal position with a pillow between the knees or lying on the back with a pillow under the knees may help.

Prescription muscle relaxants may help some patients, although their benefits are uncertain. Once started, medications should be taken on a regular schedule in order to maintain consistent effectiveness.

Massage therapy may help relieve both acute and chronic low back pain. Several well-conducted studies have shown some benefit and suggest it may reduce the costs of care. Massage therapy may not be covered by health insurance.

Spinal manipulation may help, although it is not clear if it works any better than physical therapy or general care. Some experts recommend delaying this treatment until pain has persisted for 3 weeks, if possible, since the back pain will most likely have gone away on its own by then.

Acupuncture has not proven to have any value for acute low back pain in most patients, but may provide some help for patients with chronic low back pain.

Be aware of and avoid approaches that are not helpful. Certain approaches may even be harmful for acute low back pain. For example, permanent bipolar magnets (magnet therapies) can deactivate heart devices and must be kept at least six inches away from pacemakers or implantable cardioverter defibrillators. These magnets have gained some popularity as a non-invasive method of relieving pain, but no studies support the claims.

Specific Treatment for Chronic Low Back Pain

Evidence strongly suggests that only intensive treatment, involving both physical and psychological rehabilitation programs, can reduce pain and improve function in patients with chronic low back pain. Even with the best treatments, many patients with chronic back pain fail to have complete pain relief. They often must develop methods for coping with persistent pain.

Early treatments for severe or chronic low back pain are similar to those of acute uncomplicated low back pain.

Pain relievers, particularly non-steroidal anti-inflammatory drugs (NSAIDs), may help relieve symptoms, although they can have severe effects on the gastrointestinal tract over time. Some doctors have recommended long-term opioids for patients with severe chronic pain, but studies suggest they do not improve activity levels and can have significant side effects.

Corticosteroid injections and tricyclic antidepressants may be helpful for some patients.

Specific and regular exercise under the guidance of a trained professional is important for reducing pain and improving function, although patients often find it difficult to maintain therapy.

A new type of physical therapy, called Souchard's global postural re-education, helps relieve back pain symptoms due to degenerative disk disease, according to research presented at the 2005 American Academy of Neurology Annual Meeting. The method involves stretching weakened muscles around the spine and stomach. Researchers studied 102 people who had at least 7 months of severe back pain due to disk disease and who had received different types of treatment for more than 6 months. They attended the new physical therapy sessions two times the first week, then once a week for an average of 5 months. Ninety-two percent had significant pain relief and returned to their normal daily activities. The majority of those who had pain relief felt better after 3 weeks, and remained pain free for almost 2 years.

Alternative therapies may help. Transcutaneous electrical nerve stimulation (TENS) and massage may relieve pain. Mind-body techniques such as relaxation and meditation may be help reducing stress-related pain. Cognitive-behavioral therapy helps change behavior and attitudes toward pain.

Acupuncture may provide longer-lasting pain relief than physical therapy, according to a study in the British Medical Journal. For the study, 129 people were given either 6 acupuncture or physical therapy sessions. The study authors cautioned that the benefit of acupuncture greatly depended on the health care provider’s experience. Another study, published in the Archives of Internal Medicine, reported that acupuncture worked better than no treatment at all.

Yoga relieves low back pain better than conventional exercise or self-help books, according to a study published in the December 20, 2005, issue of Annals of Internal Medicine. For the study, 101 adults with low back pain who were randomly assigned to one of three groups. One group attended yoga classes and lessons; the second did aerobics, weight training, and stretching; and third group read a self-help book about back pain. After 12 weeks, those who took yoga could better perform daily activities requiring the back than those in the other two groups. After 26 weeks, those who took yoga had less pain and better back function, and used fewer pain relievers than the others.

Patients should always try all possible non-surgical treatments before opting for surgery. The most common reasons for surgery for low back pain are sciatica and spinal stenosis. Some experts believe that less than 1% of back pain patients need aggressive medical or surgical treatments.

Nevertheless, when it is appropriate, surgery can provide great relief. Many approaches and procedures are available or being investigated. However, there have been few well-conducted studies to determine if any type of back pain surgery works better than others, or if a single procedure is better than no surgery at all.

People who are obese and have low back pain may benefit from surgical weight loss surgery. A study in the journal Obesity Surgery found that bariatric (stomach stapling) surgery significantly improves the degree of disability in morbidly obese patients who have low back pain.

Before having any surgery, it is extremely important that the patient is sure that the surgeon has had significant experience with the procedure.

Nonsurgical Procedures. Patients with herniated disks should try nonsurgical treatments for at least 1 month before considering surgery. Nonsurgical procedures include spinal manipulation, massage therapy, and physical therapy. Patients should wait at least 2 - 3 weeks before using spinal manipulation.

Surgery. According to a 2001 review of studies, about 10% of patients have such bad back pain after 6 weeks that a diskectomy may be considered. Diskectomy is the standard procedure for herniated disks. For many of these patients, surgery may bring significant relief. In one study, 70% of patients with moderate-to-severe sciatica who had had surgery reported improvement. In most patients, the improvement was better than that achieved by 4 years of nonsurgical treatments. It is not clear if surgery maintains its advantage for longer periods of time.

Preventing Falls. Falling is a risk for patients with spinal stenosis. They should avoid alcohol and sedatives. Leg strengthening exercises such as walking and cycling may be helpful.

Nonsurgical Treatments. The use of common pain relievers such as NSAIDs, physical therapy, and spinal injections may be helpful for some patients.

Surgery. If pain is persistent, patients may require surgery, most often a procedure called decompressive laminectomy. Some patients may require spinal fusion as well. Studies suggest that surgery reduces back pain in many patients with spinal stenosis, at least for a few years. However, by 4 years after surgery, 30% of patients have severe pain again, and 10% have another operation. It should be noted that surgery does not always improve outcome and, in some cases, can even make it worse. Surgery can be an extremely effective approach, however, for certain patients whose severe back pain does not respond to conservative measures.

The general approach for patients with piriformis syndrome is corticosteroid injections and physical therapy. Botox injections are showing promise.

In carefully selected patients who do not respond to physical therapy and injections, some studies report dramatic pain relief with a surgical procedure that releases the piriformis muscle.

Prognosis

Most people with acute low back pain are back at work within a month and fully recover within a few months. According to one study, about a third of patients with uncomplicated low back pain significantly improved after a week; two-thirds recovered by 7 weeks.

However, studies now suggest that up to 75% of patients suffer at least one recurrence of back pain over the course of a year. In another study, after 4 years, less than half were symptom-free. Some doctors are approaching the problem as one that is not necessarily curable and which needs a consistent on-going approach.

Specific conditions can determine the rate of improvement:

In the majority of patients with herniated disks, the condition improves (although the actual physical improvement may be slower than the reduction in pain). Researchers attempted to identify factors most likely to predict an elevated risk for recurrent pain and found that only depression was a significant factor in the majority of those who had not recovered.
Spinal stenosis stabilizes in about 70% of cases and worsens in 15%.

Studies have found that when people stay home because of back injury, only 65% are back at work within a week. Nearly 14% are still absent at one month. If someone is on disability for more than 6 months, the chance of them returning to work is only 50%.

Low back pain accounts for significant losses in work days and dollars. In 1990, it cost the U.S. $23 billion in direct medical costs and possibly as much as $85 billion in total costs (such as lost productivity). Chronic back pain has become one of the most expensive causes of disability among workers under the age of 45. One study found that, although severe back pain comprised only 10% of workers compensation cases, it accounted for 86% of compensation costs.

Complications

Certain warning signs should alert a patient to see a doctor immediately for low back pain. Any very severe back pain warrants attention, particularly if any of the following conditions are present:

Being over 50
Recent injury
Severe pain
Pain awakens the person at night
Pain accompanied by fever (possible infection)
Pain increased by lying down
Pain unrelated to movement
Pain lasts for a month, and is accompanied by unexplained fever or weight loss
History or chronic use of corticosteroids
Intravenous drug use
History of urinary tract infection
In children, any severe neck or back pain or pain that persists for more than 3 days

Cauda equina syndrome is the impingement of the cauda equina (the four strands of nerves leading through the lowest part of the spine). It is an emergency condition that can cause severe complications of the bowel or bladder. Cauda equina syndrome is usually caused by massive extrusion of the disk material. It can cause permanent incontinence if not promptly treated with surgery. Symptoms of the cauda equina syndrome include:

Dull back pain
Weakness or numbness in the buttocks, in the area between the legs, or in the inner thigh, backs of legs, or feet. May cause difficulty in standing or stumbling.
An inability to control urination and defecation
Pain accompanied by fever (can indicate an infection)

Prevention

Exercise, diet, stress, and weight all have a significant influence on back pain. Changing certain lifestyle factors can help reduce and, possibly, prevent backaches.

Smokers are at higher risk for back problems, perhaps because smoking decreases blood circulation. The link may also be due to an unhealthy lifestyle in general. A British study found that young adults who were long-term smokers were nearly twice as likely to develop low back pain as nonsmokers.

Sedentary Lifestyle. People who do not exercise regularly face an increased risk for low back pain, especially when they perform sudden, stressful activities such as shoveling, digging, or moving heavy items. Although no definitive studies have been done to prove the relationship between lack of exercise and low back pain, some doctors believe that an inactive lifestyle may be to blame in some cases. Lack of exercise leads to the following conditions that may threaten the back:

Stiff muscles can make it hard to move, rotate, and bend the back.
Weak stomach muscles can increase the strain on the back and cause an abnormal tilt of the pelvis.
Weak back muscles may increase the risk for disk compression.
Obesity puts more weight on the spine and increase pressure on the vertebrae and disks. However, studies report only a weak association between obesity and low back pain.

Improper or Intense Exercise. Improper or excessive exercise may also increase one's chances for back pain.

Some research suggests that over time, high-impact exercise may increase the risk for degenerative disk disease. A survey of people who played tennis, however, found no increased risk for low back pain or sciatica.
Between 30 - 70% of cyclists experience low back pain. One 1999 study reported that 70% of cyclists reported improvement simply by adjusting the angle of the bicycle seat.
Improper exercise instruction and inattention to body movements can lead to back trouble. For example, a single jerky golf swing or incorrect use of exercise equipment (especially free weights, nautilus, and rowing machines) can cause serious back injuries.

The way a person moves, stands, or sleeps plays a major role in back pain.

Maintaining good posture is very important. This means keeping the ears, shoulders, and hips in a straight line with the head up and stomach pulled in. It is best not to stand for long periods of time. If it is necessary, walk as much as possible and wear shoes without heels, preferably with cushioned soles. Use a low foot stool and alternate resting each foot on top of it.
Sitting puts the most pressure on the back. Chairs should either have straight backs or low-back support. If possible, chairs should swivel to avoid twisting at the waist, have arm rests, and adjustable backs. While sitting, the knees should be a little higher than the hip, so a low stool or hassock is useful to put the feet on. A small pillow or rolled towel behind the lower back helps relieve pressure while either sitting or driving.
Riding in and driving a car for long periods of time increases stress. Move the car seat as far forward as possible to avoid bending forward. The back of the seat should not be reclined more than 30 degrees. If possible, the seat bottom should be tilted slightly upward in front. A traveler should stop and walk around about every hour. Avoid lifting or carrying objects immediately after the ride.

Anyone who engages in heavy lifting should take precautions when lifting and bending.

If an object is too heavy or awkward, get help.
Spread your feet apart to give a wide base of support.
Stand as close as possible to the object being lifted.
Bend at the knees, not at the waist. As you move up and down, tighten stomach muscles and tuck buttocks in so that the pelvis is rolled under and the spine remains in a natural "S' curve. (Even when not lifting an object, always try to use this posture when stooping down.)
Hold objects close to the body to reduce the load on the back.
Lift using the leg muscles, not those in the back.
Stand up without bending forward from the waist.
Never twist from the waist while bending or lifting any heavy object. If you need to move an object to one side, point your toes in that direction and pivot toward it.
If an object can be moved without lifting, pull it, don't push.

There are four natural curves in the spinal column: the cervical, thoracic, lumbar, and sacral curvature. The curves, along with the intervertebral disks, help to absorb and distribute stresses that occur from everyday activities such as walking or from more intense activities such as running and jumping.

Can't Fall Asleep? Try These Tips

FitSugar — Thu, 16 Jul 2009 13:30:23 -0700

It's so frustrating to be lying in bed, knowing you need your beauty rest and you can't for the life of you fall asleep. So the next time you find yourself tossing and turning, try these helpful tips from fellow FitSugar readers.

"In desperate times, I do the relaxation technique I learned in yoga when you breath and focus on relaxing each little part of your body. I start with my forehead and work down. By the time I reach my hips I'm usually out." - jadfair
"Sometimes it helps me to listen to audiobooks, especially those that I've already read/heard before. It helps me block out all of the swirling end of the day thoughts and just go to sleep." - tlsgirl
Fitsugar reader laellavita says, "If I don't work out, I just feel too restless to sleep. My workout is never at night, but expelling all that energy in one hour always makes me sleep better than a whole stressful day ever does."

For other tips on getting some shuteye, read more.

"I read every night before bed, and I drink a mug of Yogi's Bedtime tea. If I still have trouble, I either start counting backwards from 500, or I've recently discovered an even happier and more peaceful method - making a mental gratitude list based on things that happened that day. I'm usually asleep by the time I reach the third one because it's so pleasant and relaxing." - scorpstar77
Kimpossible suggests listening to "soothing music such as Enya or Enigma." She also says, "If something is really strong on my mind then I write in my journal and get the thoughts out so I can clear my head in order to get to sleep."
"I try to make sure the bedroom is dark. And I tend to get too hot when I sleep, so I try to make sure my fan is on." - Spectra
"I suffered from really bad sleeplessness until I went to my doctor and she told me about 'sleep hygiene.' I got rid of the TV, the books, the alarm clock with the light up numbers, etc. - anything that could potentially keep me awake. Now I just use the bed for sleep and . . . I also take a bath, drink some tea, and turn the computer off about one and a half hours before bedtime." - cjstraus
"Lavender linen spray works for me." - sharshar
Leila07 says, "Reading a book has always worked for me. In college I used to read my history books. I would only have to read a paragraph and then I would be out! Oh and limiting my caffeine intake after lunchtime."
"I wake up at 5 a.m. everyday, it makes going to bed a whole lot easier at night." - kclulu

Highlights

Causes

People with fibromyalgia have decreased activity in opioid receptors in parts of the brain that affect mood and the emotional aspect of pain, researchers have found. This might explain why fibromyalgia patients are likely to experience depression, and are not very responsive to opioid painkillers.
Researchers have identified a conflict between sensory perception and nervous system processing in people with fibromyalgia. One study suggests that people with the condition might have greater awareness of, or less tolerance for, movement problems (such as tremor) that don't match with their expected sensory feedback. This mismatch in sensory signals might enhance the perception of pain.

Treatment

New research adds to the evidence that exercise relieves some of the symptoms of fibromyalgia. Women with fibromyalgia who took part in a program that combined aerobic, strength training, and flexibility exercises had better physical and emotional function, as well as reduced symptoms. Another study found that an at-home exercise program improved upper body pain and function, especially in women who were having functional difficulties at the beginning of the study.
An anti-convulsant medication, gabapentin (Neurontin), significantly improved pain in fibromyalgia patients compared to placebo. Patients who took gabapentin also reported that they slept better and felt less tired.
The selective serotonin-reuptake inhibitor paroxetine (Paxil) significantly lowered patient scores on a fibromyalgia symptom questionnaire, and was well-tolerated, although the drug do much for their pain.

Introduction

Fibromyalgia is a syndrome of unknown causes that results in lasting, sometimes debilitating, muscle pain and fatigue. Fibromyalgia is also known as fibrositis or fibromyositis.

Pain. The primary symptom of fibromyalgia is pain. The pain can be in one place or all over. The exact locations of the pain are called tender points. The pain of fibromyalgia is often is described as follows:

Tender point pain occurs in local sites, usually in the neck and shoulders. The pain then spreads out from these areas. The actual pain starts at the muscles. The joints are not affected. There are no lumps or nodes associated with these points of pain, and no signs of inflammation (swelling). People diagnosed with fibromyalgia feel pain in at least 11 of 18 specific tender points.
Widespread pain described as stiffness, burning, and aching. The pain also "radiates," or spreads, to nearby areas. Most patients report feeling some pain all the time. Many describe it as "exhausting." The pain can vary depending on the time of day, weather changes, physical activity, and the presence of stressful situations. The pain is often more intense after disturbed sleep.

Fatigue and Sleep Disturbances. Another major complaint is fatigue. Some patients report that fatigue is more unbearable than their pain. Sleep disturbances, particularly restless legs syndrome, are also very common. Fatigue and sleep disturbances are almost universal in patients with fibromyalgia. Some experts believe that if these symptoms are not present, doctors should seek a diagnosis other than fibromyalgia.

Depression and Mood. Up to a third of patients have depression. Disturbances in mood and concentration are also very common. These conditions often go undiagnosed in patients with fibromyalgia.

Other Symptoms. The following symptoms may also be present:

Digestive problems, including irritable bowel syndrome with gas, and alternating diarrhea and constipation
Dizziness
Painful menstrual periods
Tension or migraine headaches
Tingling or numbness in the hands and feet
Urinary frequency caused by bladder spasms

Symptoms in Children. In general, children with fibromyalgia most often have sleep disorders and widespread pain.

Causes

The most common type is primary fibromyalgia, in which the causes are not known. Many experts believe that fibromyalgia is not a disease, but rather a chronic pain condition brought on by several abnormal body responses to stress. Physical injuries, emotional trauma, or viral infections such as Epstein-Barr may be triggers of the disorder, but none have proven to be a cause of primary fibromyalgia.

Research published in the December 2006 issue of Current Pain and Headache Reports found that the areas in the brain that are responsible for the sensation of pain are different in fibromyalgia patients from the same areas in healthy people.

People with fibromyalgia have been found to have decreased activity in opioid receptors in parts of the brain that affect mood and the emotional aspect of pain. This reduced response might explain why fibromyalgia patients are likely to havedepression, and are less responsive to opioid painkillers, researchers say.

Sleep disturbances are common in fibromyalgia. Both adult and young patients with fibromyalgia have a higher-than-average rate of a sleep disorder called periodic limb movement disorder (PLMD). PLMD used to be called nocturnal myoclonus. Patients with PLMD involuntarily contract their leg muscles every 20 - 40 seconds during sleep. This may occasionally wake up the patient.

Some researchers believe that fibromyalgia does not lead to poor sleeping patterns, but that sleep disturbances come first. Researchers continue to investigate the link between fibromyalgia and sleep.

In one study, healthy volunteers reported fibromyalgia-like pain after they had been subjected to disrupted deep sleep. Disturbed sleep appears to trigger factors in the immune system that cause inflammation, pain, fatigue, and lower tolerance to pain. A 2004 study found that patients with fibromyalgia have increased rates of cyclic alternating sleep pattern (CAP). Increased CAP produced serious sleep problems, which were strongly linked to symptom severity. Previous studies have also suggested that CAP may be related to PLMD.
A 2004 report found that sleep disorders that cause breathing problems are common in women with fibromyalgia.
Other biological measures of troubled sleep, however, such as levels of the hormone melatonin, which helps regulate circadian rhythms and the sleep-wake cycle, appear to be normal in most people with fibromyalgia.

Many abnormalities of hormonal, metabolic, and brain chemical activity have been described in studies of fibromyalgia patients. Changes appear to occur in several brain chemicals, although no regular pattern has emerged that fits most patients. Since there has been no clear cause-and-effect relationship established, this may be a result of the effects of pain and stress on the central nervous system, and not a cause of fibromyalgia.

Serotonin. Of particular interest to researchers is serotonin, an important nervous system chemical messenger found in the brain, gut, and other areas of the body. Serotonin plays important roles in feelings of well-being, adjusting pain levels, and promoting deep sleep. Serotonin abnormalities have been linked to many disorders, including depression, migraines, and irritable bowel syndrome. Lower serotonin levels have also been noted in some patients with fibromyalgia.

Stress Hormones. Researchers have also found abnormalities in the hormone system known as the hypothalamus-pituitary-adrenal gland (HAP) axis. The HAP axis controls important functions, including sleep, response to stress, and depression. Changes in the HAP axis appear to produce lower levels of the stress hormones norepinephrine and cortisol. (By contrast, levels of stress hormones in depression are higher than normal.) Deficiencies in the levels of stress hormones produce impaired and weaker responses to psychological or physical stresses. (Examples of physical stress include infection or exercise.)

The hypothalamus is a highly complex structure in the brain that regulates many important brain chemicals.

Low Growth Hormone Levels. Some studies have reported low levels of insulin-like growth factor-1 (IGF-1) in about a third of fibromyalgia patients. IGF-1 is a hormone that is controlled by the adult growth hormone, and promotes bone and muscle growth. Low levels of growth hormone are related to impaired thinking, lack of energy, muscle weakness, and intolerance to cold. Studies suggest that changes in growth hormone likely stem from the hypothalamus in the brain. While researchers did not find a link between IGF-1 levels and fibromyalgia, a 2005 study indicated that serum growth hormone levels may be a marker of the disorder.

Abnormal Pain Perception and Substance P. Some studies have suggested that fibromyalgia may involve too much activity in the parts of the central nervous system that process pain (the nociceptive system). Brain scans of fibromyalgia patients have suggested abnormalities in pain processing centers. For example, researchers have detected up to three times the normal level of substance P in the cerebrospinal fluid of fibromyalgia patients. Substance P, a chemical messenger of the nervous system, is associated with increased pain perception.

Some fibromyalgia patients may also be oversensitive to external stimulation, and overly anxious about the sensation of pain. This increase in awareness is called generalized hypervigilance. One study compared patients with fibromyalgia or rheumatoid arthritis to those without chronic pain. Researchers then measured the different groups' responses to pain and noise. Of the three groups, the fibromyalgia patients were least tolerant, and most aware, of such stimuli. However, one analysis of studies on fibromyalgia found no strong support for the hypervigilance theory.

A conflict between sensory perception and nervous system processing might occur in people with fibromyalgia. Fibromyalgia patients have been found to have greater awareness of, or less tolerance for, movement problems (such as tremor) that don't match with their expected sensory feedback. This mismatch in sensory signals might enhance the perception of pain.

Fibromyalgia has symptoms that resemble those of some rheumatic illnesses, including rheumatoid arthritis and lupus (systemic lupus erythematosus). These are autoimmune diseases in which a defective immune system mistakenly attacks the body's own healthy tissue, producing inflammation and damage. The pain in fibromyalgia, however, does not appear to be due to autoimmune factors, and there is little evidence to support a role for an inflammatory response in fibromyalgia.

Although not primary causes, psychological and social factors may contribute to fibromyalgia in three ways:

They could make individuals susceptible to fibromyalgia.
They may play some role in triggering the onset of the condition.
They may perpetuate, or be responsible for, the condition.

Studies have reported a greater number of severe experiences of emotional and physical abuse in patients with fibromyalgia, compared with the general population. Most often, the abuse came from family members or partners. This suggests that post-traumatic stress disorder (PTSD) or chronic stress may play a strong role in the development of fibromyalgia in some patients. PTSD, an anxiety disorder, is a reaction to a specific traumatic event. Symptoms of this condition, which can last for years after the traumatic event, include emotional withdrawal, hopelessness, irritability, mood swings, sleep problems, inability to concentrate, and an excessive startle response to noise. Some evidence indicates that PTSD actually results in changes in the brain, possibly from long-term over-exposure to stress hormones.

Some research found muscle abnormalities in fibromyalgia patients. These problems can be classified as the following:

Biochemical abnormalities: For example, one study reported that fibromyalgia patients had lower levels of the muscle-cell chemicals phosphocreatine and adenosine triphosphate (ATP). Such chemicals regulate the level of calcium in muscle cells. Calcium is an important component in the muscles' ability to contract and relax. If ATP levels are low, calcium is not "pushed back" into the cells, and the muscle remains contracted.
Functional abnormalities: The pain and stress of the disease itself may harm muscle function.
Structural and blood flow abnormalities: Some researchers saw overly thickened capillaries (tiny blood vessels) in the muscles of fibromyalgia patients. The abnormal capillaries could produce lower levels of compounds essential for muscle function, as well as reduce the flow of oxygen-rich blood to the muscles.

To date, none of these abnormalities have a clearly defined relationship with fibromyalgia.

Risk Factors

About 3.7 million Americans have fibromyalgia. The condition affects 2% of Americans, including 3.4% of women and 0.5% of men.

Some evidence suggests that several factors may make people more susceptible to fibromyalgia. These risk factors include:

Being female
Coming from a very stressful culture or environment
Having a psychological vulnerability to stress
Having had difficult experiences in childhood

Nine out of 10 fibromyalgia patients are women. Women may be more prone to develop fibromyalgia during menopause.

The disorder usually occurs in people ages 20 - 60 years, though it can occur at any time. Some studies have noted peaks around age 35. Others note that fibromyalgia is most common in middle-aged women. In one study, cases of fibromyalgia increased with age, and reached a frequency of more than 7% among people in their 60s and 70s.

Juvenile Primary Fibromyalgia. This type of fibromyalgia appears in adolescents, typically after age 13, with a peak incidence at age 14. It is uncommon, but studies indicate that its incidence may be increasing. One study found that 1.2% of school children, all girls, met the criteria for fibromyalgia. Other studies have found an even higher frequency of fibromyalgia in children. Symptoms are similar to adult fibromyalgia, but outcomes may be better in young people.

Studies report a higher incidence of fibromyalgia among family members. It is not clear if genetic or psychological factors, or both, are involved.

One study reported that 28% of the children of mothers with fibromyalgia also develop the disorder. Offspring who developed fibromyalgia were no more likely to have psychological disorders than those who did not.
Another study noted that 66% of parents of children with fibromyalgia reported some sort of chronic pain. About 10% of them had fibromyalgia.

Diagnosis

There is no obvious, objective method for diagnosing fibromyalgia. The criteria used for studying fibromyalgia are very helpful, particularly if the patient does not have any accompanying disorder, such as depression or arthritis, which could complicate the diagnosis. Failure to meet the criteria, however, does not rule out fibromyalgia. Fibromyalgia should be suspected in any person with muscle and joint pain with no identifiable cause.

In 1990, the American College of Rheumatology (ACR) set the following criteria for the classification of fibromyalgia:

A. Widespread pain must be present for at least 3 months. This pain must appear in all of the following locations:

Both sides of the body
Above and below the waist
Along the length of the spine

B. Pain in at least 11 of 18 specific areas called tender points on the body. The pain experienced when pressing on a tender point is very localized and intensely painful (not just tender). Tender points are located in the following areas:

The left or right side of the back of the neck, directly below the hairline
The left or right side of the front of the neck, above the collar bone (clavicle)
The left or right side of the chest, right below the collar bone
The left or right side of the upper back, near where the neck and shoulder join
The left or right side of the spine in the upper back between the shoulder blades (scapula)
The inside of either arm, where it bends at the elbow
The left or right side of the lower back, right below the waist
Either side of the buttocks below the hip bones
Either kneecap

Other Factors. The ACR classification provides a guideline, but doctors will also use a patient's medical history and other symptoms to reach a diagnosis. Fibromyalgia is often diagnosed when other diseases have been excluded. Long-term symptoms that may indicate fibromyalgia include:

Fatigue
Headache
Morning stiffness
Numbness or tingling in the hands and feet
Sleep disturbance

The 18 fibromyalgia tender points are located throughout the body. According to the American College of Rheumatology, a diagnosis of fibromyalgia requires widespread body pain plus localized pain in 11 of these 18 specific points.

A doctor should always take a careful personal and family medical history, which would include a psychological profile and a history of any factors that might indicate disorders other than fibromyalgia. Such factors might include:

Infectious diseases
Muscle weakness
Physical injuries
Rashes
Recent weight change
Sexual, physical, or substance or alcohol abuse

Patients should report any drugs they take, including vitamins and over-the-counter or herbal medications.

Pressure on Tender Spots. Any physical examination for fibromyalgia requires that the doctor press firmly on all potential tender spots. They must be painful when pressed, not simply tender. In addition, for a doctor to reach a diagnosis of fibromyalgia, these tender sites should normally not show signs of inflammation (redness, swelling, or heat in the joints and soft tissue). The tender points may also change in location and sensitivity over time. A doctor, then, may recheck tender points that do not respond the first time, in patients who have other significant symptoms.

Detection of Other Causes of Symptoms. A health care provider will also examine nails, skin, mucous membranes, joints, spine, muscles, and bones to help rule out arthritis, thyroid disease, and other disorders.

No blood, urine, or other laboratory tests can provide a definitive diagnosis of fibromyalgia. If such tests show abnormal results, the doctor should look for other disorders. Tests for specific diseases depend on family histories and other symptoms. They may include:

Blood count
Sedimentation rate
Tests of certain antibodies
Thyroid and liver function tests

The doctor may suggest follow-up psychological profile testing, if laboratory results do not indicate a specific disease.

Conditions with Similar Symptoms

Between 10 - 30% of all doctor office visits are due to symptoms that resemble those of fibromyalgia, including fatigue, malaise, and widespread muscle pain. Since no laboratory test can confirm a diagnosis of fibromyalgia, doctors will usually first test for similar conditions. It should be noted that a diagnosis of many of the disorders below may not always rule out fibromyalgia, since it can accompany other common and similar conditions.

Several conditions overlap or often coexist with fibromyalgia, and have similar symptoms. It is not clear if these conditions cause fibromyalgia, are risk factors for the disorder, have causes in common with fibromyalgia, or have no relationship at all with it.

Chronic Fatigue Syndrome. There is a significant overlap between fibromyalgia and chronic fatigue syndrome (CFS). In a 2003 study, for example, 43% of CFS patients also had a diagnosis of fibromyalgia. As with fibromyalgia, the cause of CFS is unknown. A doctor can diagnose either disorder based only on symptoms reported by the patient. The two disorders share most of the same symptoms. They are also treated almost identically. The differences are primarily the following:

Pain with tender points is the primary symptom in fibromyalgia. Some patients with CFS exhibit similar tender pressure points. However, muscle pain is less prominent in patients with CFS.
Fatigue is the dominant symptom in CFS. It is severe and not relieved by rest or sleep, and it is not the result of excessive work or exercise.

Some doctors believe that fibromyalgia is simply an extreme type of chronic fatigue syndrome. There Some physical evidence, however, indicates that the two disorders are distinct, with treatments that are specific to each.

Myofascial Pain Syndrome. Myofascial pain syndrome can be confused with fibromyalgia and may also accompany it. Unlike fibromyalgia, myofascial pain tends to occur in trigger points, as opposed to tender points, and typically there is no widespread, generalized pain. Trigger-point pain occurs in tight muscles, and when the doctor presses on these points, the patient may experience a muscle twitch. Unlike tender points, trigger points are often small lumps, about the size of a pencil eraser.

Major Depression. The link between psychological disorders and fibromyalgia is very strong and problematic. Certain studies report that 50 - 70% of fibromyalgia patients have a lifetime history of depression. Only 18 - 36% of fibromyalgia patients, however, also have major depression, a severe form of depression.

Some studies found that people who have both psychological disorders and fibromyalgia are more likely to seek medical help, compared with patients who simply have symptoms of fibromyalgia. If this is the case, study results may be biased, favoring a higher-than-actual association between depression and fibromyalgia.

Depression most likely does not cause fibromyalgia, but it may increase susceptibility. Depressed feelings in people with fibromyalgia can certainly be normal responses to the pain and fatigue caused by this syndrome. Such emotions, however, are temporary and related to the situation a person is in. They are not considered to be a depression disorder. Unlike ordinary periods of sadness, an episode of major depression disorder can last many months.

Symptoms of major depression include the following:

Depressed mood every day
Feeling worthless or inappropriately guilty
Inability to concentrate or make decisions
Insomnia or excessive sleeping
Low energy every day
Restlessness or a sense of being slowed down
Significant weight gain or loss (of 10% or more of an individual's typical body weight)
Suicidal thoughts

If several of the above symptoms are present, and none of the physical symptoms (particularly the tender points) of fibromyalgia exist, the condition is most likely major depression.

Chronic Headache. Chronic primary headaches such as migraines are common in fibromyalgia patients. Some experts believe that migraine headaches and fibromyalgia may even share common defects in the systems that regulate certain chemical messengers in the brain, including serotonin and epinephrine (adrenaline). Low levels of magnesium have also been noted in patients with both fibromyalgia and migraines. In fact, chronic migraine sufferers who fail to benefit from usual therapies may also have fibromyalgia.

Symptoms of a migraine attack may include heightened sensitivity to light and sound, nausea, vision problems (auras), speech difficulty, and intense pain predominating on one side of the head.

Multiple Chemical Sensitivity. Multiple chemical sensitivity (MCS) is a term that describes conditions in which certain chemicals can cause symptoms similar to CFS or fibromyalgia in some people. Still, as with CFS and fibromyalgia, some experts are uncertain whether MCS is a medical condition or if it is psychologically based.

In one study, for example, CFS patients who believed their problem was chemically triggered were exposed to either an active chemical or a placebo (an inactive substance). Both groups reported symptoms, including those only exposed to a placebo. Because everyone is exposed to many chemicals on a daily basis, it is very difficult to determine whether chemicals are responsible for specific symptoms.

Experts have come up with criteria to help recognize MCS:

Symptoms can be produced by exposure to the chemical at levels lower than previously or usually tolerated.
Symptoms can be triggered by multiple substances that are chemically unrelated.
Symptoms involve multiple organ systems.
The condition is chronic.
The symptoms always happen with repeated exposure to a chemical. (These are often common chemicals found in popular products, such as perfumes, fabric softeners, and air fresheners.)
The symptoms improve when the chemical is removed.

Restless Legs Syndrome. About 15% of people with fibromyalgia have restless legs syndrome. Restless legs syndrome is an unsettling and poorly understood movement disorder that is sometimes described as a sense of unease and weariness in the lower leg that is aggravated by rest and relieved by movement.

Disorders Affected by the Sympathetic (also called Autonomic) Nervous System. Other conditions that commonly accompany fibromyalgia include:

Chest pain and heart palpitations
Mitral valve prolapse
Sudden drop in blood pressure

Certain stress-related disorders commonly occur with fibromyalgia, and have overlapping symptoms. In fact, some experts believe these disorders so often interact that they may all be part of one general condition.

Chemicals and environmental toxins -- exposure to various chemicals and environmental toxins such as solvents, pesticides, or heavy metals (cadmium, mercury, or lead) can cause fatigue, chronic pain, and other symptoms of fibromyalgia.
Irritable bowel syndrome
Osteoarthritis -- a common form of arthritis than can coexist with fibromyalgia. The two conditions may be confused, particularly in elderly people. Osteoarthritis, however, causes joint pain, not widespread or generalized pain.

Osteoarthritis is a chronic disease of the joint cartilage and bone. It is often thought to result from "wear and tear" on a joint, although there are other causes, such as congenital defects, trauma, and metabolic disorders. Joints appear larger, are stiff and painful, and usually feel worse the more they are used throughout the day.

Temporomandibular joint disorders

Some tests may be positive for one or more of these diseases. However, if the results are uncertain or weak, or if these conditions have been treated successfully, fibromyalgia should not be ruled out if the patient still meets the criteria for it.

Multiple sclerosis. This condition may have symptoms similar to those of fibromyalgia. Magnetic resonance imaging (MRI) scans often detect patches of tissue in the brain that confirm the presence of multiple sclerosis (MS). MRI findings combined with other tests and clinical findings usually make this diagnosis fairly certain. However, some patients may have symptoms that suggest MS, but diagnostic tests cannot confirm the diagnosis. Some of these patients may have symptoms similar to those of fibromyalgia.

Sjogren syndrome. This condition, characterized by dry eyes and mouth, is sometimes mistaken for fibromyalgia.

Autoimmune diseases. Rheumatoid arthritis, systemic lupus erythrometosis, and Sjogren syndrome are usually easy to diagnose but may develop slowly and be difficult to diagnose at first. Even if a doctor determines that a patient is most likely to have fibromyalgia, the doctor should keep track of any changes in symptoms over time in case one of these other illnesses is actually present.

Lyme Disease. Lyme disease is a bacterial disease transmitted by ticks. Health care providers can usually diagnose early Lyme disease correctly, but a delayed response or recurrence of this disorder may be mistaken for fibromyalgia. Some experts believe that 15 - 50% of patients referred to clinics for Lyme disease actually have fibromyalgia. Late Lyme disease can usually (but not always) be ruled out using blood tests that identify the organism that causes this disease. If fibromyalgia patients are incorrectly diagnosed and treated for Lyme disease with prolonged courses of antibiotics, the drugs may have serious side effects.

Drugs and Alcohol. Fatigue is a side effect of many prescription and over-the-counter medications, such as antihistamines. In addition, symptoms of dependency on, or abuse of, alcohol or drugs appear as constant fatigue. Health care providers should consider medications as a possible cause of fatigue if an individual has recently started, stopped, or changed medications. Withdrawal from caffeine can produce depression, fatigue, and headache.

Polymyalgia Rheumatica. Polymyalgia rheumatica is a condition that causes pain and stiffness, and generally occurs in older women. Tender points are also present with this disorder, although they almost always occur in the hip and shoulder area. Morning stiffness is common, and patients may also experience fever, weight loss, and fatigue. A higher-than-normal erythrocyte sedimentation rate (ESR) can suggest polymyalgia rheumatica. Elevated ESR, however, also occurs with other conditions. Polymyalgia rheumatica often gets better in about a year, but there is a risk of persistent disease. Worse, it is sometimes associated with a rare condition called temporal arteritis, which may cause blindness if not treated, so an accurate diagnosis of polymyalgia rheumatica is important.

Prognosis

Fibromyalgia can be mild or disabling, and the emotional toll can be substantial. About half of all patients have difficulty with routine daily activities, or are unable to perform them. An estimated 30 - 40% of patients have had to quit work or change jobs. In a 2003 study, patients with either CFS or fibromyalgia were more likely to suffer losses of jobs, possessions, and support from friends and family than were people suffering from other conditions that caused fatigue.

The pain, emotional consequences, or sleep disturbances that come with fibromyalgia may lead to self-medication and overuse of sleeping pills, alcohol, drugs, or caffeine.

Outlook in Adults. Some studies show that fibromyalgia symptoms remain stable over the long term, while others report a better outlook, with 25 - 35% of patients reporting improvement in pain symptoms over time. Studies suggest that regular exercise specifically improves the outlook. Those with a significant life crisis, or who were on disability, had a poorer outcome than others. Outcome was determined by improvements in the patients' ability to work, their own feelings about their condition, pain sensation, and levels of disturbed sleep, fatigue, and depression. Although the disease is life-long, it does not get worse and is not fatal.

Outlook in Children. Children with fibromyalgia tend to have a better outlook than adults with the disorder. Several studies reported that more than half of children with fibromyalgia recover in 2 - 3 years.

Treatment

Many patients with fibromyalgia are treated first with medication; however, the American Pain Society Fibromyalgia Panel recommends a combined approach using cognitive-behavioral therapy, education, medication, and exercise.

Fibromyalgia is a mysterious condition. Its causes are still largely unknown, as is how it inflicts damage. No strong evidence indicates that any single treatment (or combination of treatments) has any significant effect for most patients. However, in 2007 the U.S. Food and Drug Administration approved pregabalin (Lyrica) as the first drug treatment for fibromyalgia after a study showed the medicine reduced fibromyalgia pain by at least 50% in 63% of patients.

Treatment usually involves not only relieving symptoms but also changing a pateint's attitude about their disease. Treatment should also teach patients behaviors that help them cope.

Treatments usually involve trial and error:

Patients may start with physical therapy, exercise, stress reduction techniques, and cognitive-behavioral therapy.
If these methods fail to improve symptoms, an antidepressant or muscle relaxant may be added to the treatment. Doctors usually prescribe these drugs because they can may improve pain tolerance.
Patient education and programs that encourage coping skills are an important part of any treatment plan.

According to a 2005 study published in the Clinical Journal of Pain, a combination of non-drug therapies works just as well as drug therapy in improving pain, depression, and disability. This combination includes exercise, stress management, massage, and diet.

Patients must have realistic expectations about the long-term outlook of their condition, and their own individual abilities. It is important to understand that fibromyalgia can be managed, and patients can live a full life. The following tips may be helpful when starting a treatment program for fibromyalgia:

The goal of therapy is to relieve symptoms, not cure them.
Treatment must be tailored to each patient, and a combination approach is often needed.
Patients must begin all treatments with the attitude that these treatments are trial-and-error. There is no clear treatment solution. Patients and doctors need to work together to make the best choices for individual symptoms and concerns.
Treatments are long-lasting, in some cases life-long, and patients should not be discouraged by the return of symptoms (relapses).
Enlisting family members, partners, and close friends, particularly to help with exercise and stretching programs, can be helpful.
Becoming involved with support groups of fellow patients also benefits many patients. Support groups may also benefit family members, particularly parents of children with fibromyalgia. One study noted that the severity of the disorder increased in children whose parents were less able to cope with their child's pain.

The definition of improvement is personal. For example, some patients are pleased with only a 10% reduction in pain and other symptoms.

Lifestyle Changes

Many studies have shown that exercise is the most effective component in managing fibromyalgia, and patients must expect to take part in a long-term exercise program. Physical activity prevents muscle wasting, increases well-being, and, over time, reduces fatigue and pain. Many studies have also demonstrated the exercise can improve physical and emotional function, as well as reduce symptoms, including pain.

Programs often combine aerobic, strength-training, and flexibility exercises with self-management education. Some studies have shown improvements lasting for up to 9 months after the exercise program.

Graded Exercise. The basic approach used for fibromyalgia is called graded exercise. Graded exercise means you slowly increase the amount of your physical activity.

In general, graded exercise involves:

A very gradual program of activity, beginning with mild exercise and building in intensity over time.
Stretching exercises before exercising. A daily stretching routine can help relax tense muscles and prevent muscle soreness.
Walking, swimming, and using equipment such as treadmills or stationary bikes. Swimming and water therapy are good because they don't require putting weight on the joints.

Patients who try hard exercises too early actually experience an increase in pain, and are likely to become discouraged and quit.

Every patient must be prepared for relapses and setbacks, but should not get discouraged. Patients who do not respond to one type of exercise might consider experimenting with another form.

Physical therapy can be very helpful. Studies suggest that physical therapy may reduce muscle overload, lessen fatigue from poor posture and positioning, and help condition weak muscles.

Sleep is essential, particularly since sleep disruptions worsen pain. Many patients with fibromyalgia have trouble getting a restful and healing night's sleep. Those who are unable to sleep consistently have low improvement. Swing shift work, for example, is extremely hard on fibromyalgia patients. Poor sleep habits can add to sleep problems. Tips for good sleep habits include:

Avoid caffeine or alcohol 4 - 6 hours before bedtime.
Avoid drinking fluids right before bedtime so that needing to uriniate does not disturb your sleep.
Avoid exercising 6 hours before bedtime.
Avoid large meals before bedtime. A light snack, however, may help you sleep.
Avoid naps, especially in the evening or late afternoon.
Establish a regular time for going to bed and getting up in the morning. Maintain this schedule even on weekends and during vacation.
If you are unable to fall asleep after 15 or 20 minutes, go into another room and start a quiet activity. Return to bed when you feel sleepy.
Minimize light and maintain a comfortable, moderate temperature in the bedroom. Keep the bedroom well ventilated.
Use the bed only for sleep and sexual relations.

[For more information see In-Depth Report #27: Insomnia.]

Fibromyalgia patients should maintain a healthy diet low in animal fat and high in fiber, with plenty of whole grains, fresh fruits, and vegetables. Although everyone should be careful about calories from fats, some are healthy.

Omega-3 Fatty Acids. Oils containing omega-3 fatty acids are of particular interest for arthritic pain. Such oils are found in cold-water fish. You can also purchase these oils as supplements called EPA-DHA or omega 3.

Omega-3 fatty acids are a form of polyunsaturated fat that the body gets from food. Omega-3s are known as essential fatty acids (EFAs) because they are important for good health. These healthy fatty acids can be found in certain fish, dark green leafy vegetables, and some oils. Omega-3 fatty acids have anti-inflammatory properties, which help prevent blood clots, lower cholesterol and triglyceride levels, and reduce blood pressure. Omega-3s may also reduce the risks and symptoms of diabetes, stroke, rheumatoid arthritis, asthma, inflammatory bowel disease, ulcerative colitis, some cancers, and mental decline.

Vegetarian Diet. A vegan diet has no meat, dairy, or eggs and includes uncooked fruits, vegetables, nuts, and germinated seeds. The actual benefit of various vegetarian diets remains unproven.

Relaxation and stress-reduction techniques are proving to be helpful in managing chronic pain. Evidence shows that people with fibromyalgia have a more stressful response to daily conflicts and encounters than those without the disorder. Several relaxation and stress-reduction techniques may be helpful in managing chronic pain:

Biofeedback
Deep breathing exercises
Hypnosis
Massage therapy
Meditation
Muscle relaxation techniques

Biofeedback. Evidence from controlled trials does not suggest that biofeedback techniques may be very helpful for fibromyalgia patients. During a biofeedback session, electric leads are taped to a subject's head. The person is encouraged to relax using any method that works. Brain waves are measured and an audio signal sounds when alpha waves are detected. Alpha waves are brain waves that occur with a state of deep relaxation. By repeating the process, people using biofeedback connect the sound with the relaxed state, and learn to achieve relaxation on their own.

Meditation. Meditation, used for many years in Eastern cultures, is now widely accepted in this country as an effective relaxation technique. A number of studies are reporting its benefits for fibromyalgia patients who practice on a continued and regular basis. The practiced meditator can achieve the following physical benefits:

Reduced heart rate, blood pressure, adrenaline levels, and skin temperature while meditating.
Improved well-being.
Better sleep -- some research has reported an increase in melatonin levels in experienced meditators. Melatonin is important in regulating the sleep-wake cycle.
Less pain, possibly from reductions in levels of cortisol, a stress hormone.

An important goal for both religious and therapeutic meditation practices is to quiet the mind, essentially to relax thought. This redirection of brain activity from thoughts and worries to the senses disrupts the stress response and prompts relaxation and renewed energy. Several meditation techniques are available. Some may be more useful for fibromyalgia than others.

Breath meditation. Other meditative forms involve focusing on the present moment and observing (but not examining or judging) one's thoughts. During breath meditation, one sits upright with the spine straight and the eyes closed. The subject begins to breathe regularly and continues to observe the outward exhalation of the breath. As the mind wanders, one simply notes the thoughts as a fact and returns to the breath. A variant of this technique called mindfulness meditation has been helpful for fibromyalgia patients. It involves focusing on the present moment and letting thoughts pass without the accompanying breathing exercises.
Fixed point meditation involves focusing on a stationary object, mental image (such as a candle flame), or internal sound (such as a mantra). When the mind begins to wander, the meditator gently brings concentration back to the central image or sound. This exercise promotes focus, but it is often experienced as a thinking exercise. A popular variety of this type of meditation is known as transcendental meditation, or TM.
Mini-meditation. This method involves heightening awareness of the immediate surrounding environment. One should first choose a simple routine activity when alone. For example, while washing dishes concentrate on the feel of the water and dishes. Allow the mind to wander to any immediate sensory experience, such as sounds outside the window, smells from the stove, or colors in the room. If the mind begins to think about the past or future, abstractions, or worries, redirect it gently back.

People who try meditation for the first time should understand that it can be difficult to quiet the mind, and should not be discouraged by lack of immediate results. Some recommend meditating for no longer than 20 minutes in the morning after awakening and then again in the early evening before dinner. Even once a day is helpful. A person should probably not meditate before going to bed, because it causes some people to wake up in the middle of the night, alert and unable to return to sleep.

Hypnosis. In one small, short-term controlled study, hypnosis was more effective than physical therapy in improving function and reducing pain.

Massage Therapy. Massage therapy is thought to stimulate the parasympathetic nervous system, which slows down the heart and relaxes the body. In one study, patients who were given 30-minute massage sessions twice a week experienced lower stress and anxiety and less pain after 5 weeks compared to a group receiving an alternative therapy called transcutaneous electrical stimulation (TENS).

Because of the difficulties in treating fibromyalgia, many patients seek alternative therapies. Everyone should be wary of those who promise a quick cure or urge the purchase of expensive but potentially dangerous treatments.

Although some studies have reported benefit from these treatments, there is not enough evidence to recommend them. In one analysis, evidence was weakest on the advantages of so-called manipulative ("hands-on") approaches, such as chiropractic treatments.

Acupuncture. Studies continue to report conflicting results on acupuncture's ability to relieve pain. Several small studies suggest that it offers some benefit, especially to those who cannot take medicines because of their side effects. A larger controlled study found that inserting needles at fibromyalgia-related pressure points was no better at relieving pain for fibromyalgia than randomly inserting needles ("sham acupuncture"). A 2006 review of five randomized, controlled trials did not find enough evidence to support the use of acupuncture for fibromyalgia.

Chiropractic or Osteopathic Manipulation. Chiropractic or osteopathic manipulation may also help some patients. While some studies have reported pain relief and improved sleep with osteopathic manipulation, larger controlled studies are needed to clearly identify whether manipulation is an effective treatment. Osteopathic techniques may include manipulation of the spine or muscle tissue release. Note that there is always some very small risk for adverse effects from any of these techniques. For example, in rare cases manipulation of the neck has caused stroke or damage to the large blood vessels in the neck.

Hydrotherapy and Similar Treatments. Hydrotherapy, also called balneotherapy, involves soaking in water, such as hot tubs, pools, or baths, to help relieve pain.

Herbal or Natural Remedies. Some alternative agents are being investigated for fibromyalgia:

Melatonin, a natural hormone associated with the sleep-wake cycle, may have benefits for some patients with fibromyalgia.
S-adenosylmethionine (SAMe) is a natural substance that has antidepressant, anti-inflammatory, and analgesic properties. It has shown some benefit in controlled studies.

It is extremely important for patients to realize that any herbal remedy or natural medicine that has positive effects most likely has negative side effects and toxic reactions, just as any conventional drug does. You should consult a doctor before using any untested products or dietary supplements. You should also discuss with your doctor any potential interactions between the supplements and any medications you take.

Generally, manufacturers of herbal remedies and dietary supplements do not need approval from the U.S. Food and Drug Administration to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been a number of reported cases of serious and even deadly side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements.

Behavioral Therapy

Studies continue to show that fibromyalgia patients feel better when they deal with the specific conditions of their disorder and their lives. Cognitive-behavioral therapy (CBT) enhances a patient's belief in their own abilities and helps them develop methods for dealing with stressful situations. CBT, also called cognitive therapy, is a known, effective method for dealing with chronic pain from arthritic conditions. Some evidence also suggests that cognitive-behavioral therapy can help some patients with fibromyalgia.

Although the effects of CBT and other non-medication treatments for fibromyalgia do not always last over the long-term, they may help certain groups of people, particularly those with a high level of psychological stress.

CBT may be particularly useful for addressing insomnia, one of the hallmark symptoms of fibromyalgia. Patients who received CBT for insomnia woke up 50% less at night, and had fewer symptoms of insomnia and improved mood.

The Goals of CBT. The primary goals of CBT are to change any unclear or mistaken ideas and self-defeating behaviors. Using specific tasks and self-observation, patients learn to think of pain as something other than a negative factor that controls their life. Over time, the idea that they are helpless against the pain goes away and, instead, they learn that they can manage the pain.

Cognitive therapy is particularly helpful in defining and setting limits -- a behavior that is extremely important for these patients. Many fibromyalgia patients live their lives in extremes. They first become heroes or martyrs, pushing themselves too far until they collapse. This collapse reverses the way they view themselves, and they then think of themselves as complete failures, unable to cope with the simplest task. One important aim of cognitive therapy is to help such patients discover a middle route. Patients learn to prioritize their responsibilities and drop some of the less important tasks or delegate them to others. Learning these coping skills can eventually lead to a more manageable life. Patients learn to view themselves and others with a more flexible attitude.

The Procedure. Cognitive therapy usually does not last long, typically 6 - 20 one hour sessions. Patients also receive homework, which usually includes keeping a diary and trying tasks they have avoided because of negative attitudes.

A typical cognitive therapy program may involve the following measures:

Keep a Diary. Patients are usually asked to keep a diary, a key part of cognitive therapy. The diary serves as a general guide for setting limits and planning activities. Patients use the diary to track any stress factors, such as a job or a relationship that may be making the pain worse or better.
Confront Negative or Discouraging Thoughts. Patients are taught to challenge and reverse negative beliefs. For example, "I'm not good enough to control this disease, so I'm a total failure" becomes the coping statement, "Where is the evidence that I can control this disease?"
Set Limits. Limits are designed to keep both mental and physical stress within manageable levels, so that patients do not become discouraged by getting "in over their heads." For example, tasks are broken down into incremental steps, and patients focus on one at a time.
Seek out Pleasurable Activities. Patients list a number of enjoyable low-energy activities that they can conveniently schedule.
Prioritize. Patients learn to drop some of the less critical tasks or delegate them to others.

Patients should learn to accept that relapses occur, and that over-coping and accomplishing too much too soon can often cause a relapse of symptoms. Patients should respect these relapses and back off. They should not consider them a sign of failure.

Research also shows that patient education can be effective in treating fibromyalgia, especially when combined with CBT, exercise, and other therapies. Educational programs can take the form of group discussions, lectures, or printed materials, although there isn't any clear evidence on which type of education works best.

Cognitive therapy may be expensive and not covered by insurance. Alternative and effective approaches that are free or less costly include strong, intelligently managed support groups or group psychotherapy. In one center, educational discussion groups were as effective, or even more so, than a cognitive therapy program. Such results are not typical in all centers, of course. Therapeutic success varies widely depending on the skill of the therapist.

Medications

Typically the first choice in drug treatment of fibromyalgia has consisted of an antidepressant or a muscle relaxant. The goal has been to improve sleep and pain tolerance. Medications from other drug classes (such as sleeping aids and pain relievers) may also be prescribed. Patients receive drug treatments in combination with exercise, patient education, and behavioral therapies. In 2007 the Food and Drug Administration approved Pregabalin (Lyrica) as the first drug for the treatment of fibromyalgia.

Pregabalin is an anti-epileptic. Also called anti-seizure drugs and anti-convulsants, these medicines affect the chemical messenger gamma aminobutyric acid (GABA), which helps prevent nerve cells from over-firing.

Pregabalin was previously approved in 2004 to treat nerve pain and diabetic peripheral neuropathy. A 2005 study of 529 patients with fibromyalgia reported that 450 mg per day of pregabalin reduced pain and improved sleep quality and fatigue symptoms. Study results presented in November 2006 showed pregabalin cut fibromyalgia pain by at least 50% in 63% of patients, and the effect was long-lasting. The study, lasting 6 months, was one of the longest controlled studies of pregabalin in fibromyalgia to date. The most common side effects include mild-to-moderate dizziness and sleepiness. Pregabalin can impair motor function and cause problems with concentration and attention. Patients should talk to their doctor about whether pregabalin may impair their ability to drive.

Studies have shown that another anti-convulsant, gabapentin (Neurontin), which is approved for treatment of postherpetic neuralgia, affects pain transmission pathways and may relieve pain associated with fibromyalgia when compared with placebo. Patients who took gabapentin also reported that they slept better and were less tired.

The main classes of antidepressants used for treating fibromyalgia are tricyclics, selective serotonin-reuptake inhibitors (SSRIs), and serotonin-norepinephrine reuptake inhibitors (SNRIs). Although these drugs are antidepressants, doctors prescribe them to improve sleep and relieve pain in non-depressed patients with fibromyalgia. The dosages used for managing fibromyalgia are generally lower than dosages prescribed for treating depression. If a patient has depression in addition to fibromyalgia, higher doses may be required.

Tricyclics. Tricyclic antidepressants cause drowsiness and can be helpful for improving sleep. The tricyclic drug most commonly used for fibromyalgia is amitriptyline (Elavil, Endep), which produces modest benefits with pain, but which can lose effectiveness over time. Other tricyclics include desipramine (Norpramin), doxepin (Sinequan), imipramine (Tofranil), amoxapine (Asendin), and nortriptyline (Pamelor, Aventyl).

Generally, only small doses of tricyclic antidepressants are needed to relieve fibromyalgia. Therefore, although tricyclics have several side effects, these side effects may be less frequent in fibromyalgia patients than in those taking tricyclics for depression. Side effects most often reported include:

Blurred vision
Difficulty urinating
Dizziness
Drowsiness
Dry mouth
Heart rhythm disturbances
Sexual dysfunction
Weight gain

As with all medications, tricyclics must be taken as directed. An overdose can be life-threatening.

Unfortunately, not all patients respond to tricyclics, and their effects wear off in some patients, sometimes after only a month.

Selective Serotonin-Reuptake Inhibitors. Selective serotonin-reuptake inhibitors (SSRIs) increase serotonin levels in the brain, which may have specific benefits for fibromyalgia patients. Commonly prescribed SSRIs include fluoxetine (Prozac), sertraline (Zoloft), paroxetine (Paxil), and fluvoxamine (Luvox). Studies suggest they may improve sleep, fatigue, and well-being in many patients. Studies are mixed on whether they improve pain. SSRIs should be taken in the morning, since they may cause insomnia. Common side effects are agitation, nausea, and sexual dysfunction, including delay or loss of orgasm and low sex drive.

Serotonin-Norepinephrine Reuptake Inhibitors. Serotonin-norepinephrine reuptake inhibitors (SNRIs) are also known as dual inhibitors because they act directly on two chemical messengers in the brain -- norepinephrine and serotonin. These drugs include:

Duloxetine (Cymbalta) is gaining attention as a treatment for fibromyalgia. In a 2004 study, 207 patients with fibromyalgia were randomized to receive either 60 mg of duloxetine twice a day or placebo for 12 weeks. Duloxetine significantly improved pain and tenderness and was effective for both depressed and non-depressed patients. Duloxetine was most effective for women, but very few men were enrolled in this trial.
Venlafaxine (Effexor) is similar to fluoxetine (Prozac) in effectiveness and tolerability for most patients. As with SSRIs, and unlike other newer antidepressants, venlafaxine impairs sexual function. Although clinical trials have shown that the drug is safe and effective in most people, there have been reports of changes in blood pressure. There have also been reports of problems with the electrical system of the heart when taking this drug. These side effects may cause serious problems in elderly patients. Some patients report severe withdrawal symptoms, including dizziness and nausea.
Milnacipran (Ixel) is under investigation and is not yet approved in the United States. It is specifically being researched for helping people with fibromyalgia and similar pain syndromes. In a 2004 study of 125 patients, milnacipran improved fibromyalgia pain and other symptoms, including fatigue, sleep, and depression.

Cyclobenzaprine (Flexeril) relaxes muscle spasms in specific locations without affecting overall muscle function. Cyclobenzaprine is related to the tricyclic antidepressants and has similar side effects, including drowsiness, dry mouth, and dizziness. A 2004 review of five randomized controlled trials found that patients who received cyclobenzaprine were three times more likely to report improvement in fibromyalgia symptoms than patients who received placebo.

Zolpidem (Ambien) or other newer sleep medications such as zaleplon (Sonata) and eszopiclone (Lunesta) may improve sleep for patients who suffer from insomnia.

Pain relief is of major concern for patients with fibromyalgia. Pain relievers for fibromyalgia include:

Tramadol (Ultram), used alone or in combination with acetaminophen (Tylenol), is commonly prescribed for relief of fibromyalgia pain. Its most common side effects are drowsiness, dizziness, constipation, and nausea. Tramadol should not be used in combination with tricyclic antidepressants.
For relief of mild pain, acetaminophen is most often recommended. Anti-inflammatory drugs, which are commonly used for arthritic conditions, are less useful for the pain of fibromyalgia, since the pain is not caused by muscle or joint inflammation. Anti-inflammatory drugs include corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin and ibuprofen (Advil).
Capsaicin (Zostrix) is an ointment prepared from the active ingredient in hot chili peppers. Capsaicin is helpful in relieving painful areas in other disorders. It may have some value for fibromyalgia patients.
Opioids, or narcotics, may be used occasionally by certain patients with moderate-to-severe pain, or those with significant problems performing everyday tasks. Such patients should use narcotics only if they cannot find relief with other, less potent treatments. Some patients may get combinations of narcotic pain relievers and acetaminophen for periodic pain. Some physicians prescribe opioids, such as oxycodone (Roxicodone) or morphine sulfate (Duramorph), for patients who need ongoing relief. However, the benefit of opioids in fibromyalgia treatment is highly controversial. Physicians should take a careful medical and psychological profile of the patient before prescribing opioids. The patients should be evaluated periodically for continuing pain relief, side effects, and indications of dependence.
Pramipexole, a drug used to treat Parkinson’s disease and restless legs syndrome, may help relieve pain and fatigue in people with fibromyalgia, according to one study. Pramipexole stimulates production of dopamine, a chemical messenger in the brain. Researchers compared pramipexole with a dummy pill (placebo). After 3.5 months, 36% of those who took pramipexole said they felt much better, compared to 9% of those who received a dummy pill. Overall, patients had a 50% or greater decrease in pain.
One small 2005 study conducted in Spain suggests that the atypical antipsychotic olanzapine (Zyprexa) may be a beneficial add-on therapy for patients with fibromyalgia. Although proven effective for some chronic pain conditions, olanzapine and other antipsychotics cause unpleasant and potentially serious side effects.

Tropisetron. Tropisetron (Navoban) is a drug used to reduce vomiting during chemotherapy. European studies suggest that it may also help patients with fibromyalgia by reducing pain, dizziness, and depression, and by improving sleep. Fatigue and dizziness are the most common side effects.

Much of the pain patients experience occurs where muscles join tendons or bones, particularly when the muscles are stretched. Stretching or flexibility exercises are part of the warm-up and cool-down routines of any regular exercise program. Stretching techniques may also use injections or cooling agents to inactivate the pressure points so that muscles can be more effectively stretched. These techniques must be performed by a person other than the patient, usually a family member or close friend. With either injections or the spray, the benefits may last from a few days to weeks. Neither the spray nor the injection is useful without muscle stretching.

Spray and Stretch. One technique is known as "spray and stretch." This method uses the following approach:

The patient must be in a comfortable position.
The partner presses on suspected tender points and the patient reports any pain.
The points, when targeted, are sprayed with either ethyl chloride (Chloroethane) or Fluori-Methane. These chemicals are not numbing medicines. They cool the blood vessels in the skin to inactivate the tender points. Numbing skin creams do not appear to be effective for this treatment.
The spray bottle is held upside-down about 12 - 18 inches from the targeted area. The patient's face should be covered if the spray is being used near the head.
The patient's partner then slowly stretches the affected muscle.

After the procedure, the muscle should feel looser, and the patient should have a greater range of motion with that muscle.

Trigger-Point Injections. In some cases, "trigger-point injections" of a numbing drug, such as lidocaine, may be used for particularly painful tender points as an aid to stretching.

The injection causes intense, but brief, pain in the trigger point. After the medication has taken effect, however, the muscle's ability to stretch is much greater.
There is some soreness afterward, which can be severe. After an injection, spraying the whole muscle with cooling agents may inactivate less severe tender points.
In some cases, injections may be needed several times over 6 - 8 weeks.
