Why Does My Lower Back Hurt During My Period?

Back Pain During Your Period? Here's How to Make It Stop

As if pimples, emotional outbursts, cramps, exhaustion, and feeling bloated aren't enough, the PMS demons have to throw uncomfortable back pain your way too.

Lower back pain during your period, or primary dysmenorrhea, is caused by contractions in the uterus. Every month your body builds up a thick uterine lining (called endometrium) in preparation for a fertilized egg. If you don't become pregnant, estrogen and progesterone levels drop and cue your body to break down and detach the lining, and it does that by contracting. If your uterus contracts too strongly, it can press on nearby blood vessels, cutting off the supply of oxygen to the nearby muscles, which is the reason pain occurs in the abdomen and radiates to the lower back and even to the thighs.

Chances are, if you've always had similar menstrual discomfort, it's nothing to worry about. But see a doctor if you're incapacitated for more than a few days a month or if you've noticed a sudden change in your symptoms. Meanwhile, you can ease the back pain with over-the-counter anti-inflammatory drugs such as ibuprofen, or try a warm bath or a heating pad. Avoiding foods that contain caffeine and salt can also help. And even though you have about as much energy as it takes to plop onto the couch, women who exercise regularly often experience less menstrual pain, so keep up with your routine by doing some light cardio or these cramp-relieving yoga poses.
