The exact causes of migraine headaches -- vascular headaches associated with changes in the size of arteries within and outside the brain -- are unknown. People with migraines may inherit the tendency to be affected by migraine triggers, including fatigue, weather changes and bright lights.
Pain relievers like acetaminophen (Tylenol) and nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin, ibuprofen (Motrin) and naproxen sodium (Aleve) may help reduce migraine symptoms. Stronger medications including triptans and ergotamine derivatives are available by prescription from your doctor.
