Headache
HEALTH GUIDE REFERENCE FROM A.D.A.M
Headaches are usually caused by either muscle tension, vascular problems, or both. Migraines are vascular in origin, and may be preceded by visual disturbances, loss of peripheral vision, and fatigue. Most headaches can be relieved or ameliorated by over-the-counter pain medications.
