[sidebar]Developed by neurologists at New York’s Albert Einstein College of Medicine, the ID Migraine quiz may help the 14 million Americans who have undiagnosed migraines. Most are women, and 90% don’t have migraine’s telltale warning: an eerie visual disturbance called an aura. To see if your headache is really a migraine, answer these questions:  1. Does light bother you when you have a headache? 2. Do you get nauseated or sick to your stomach when you have a headache? 3. Has a headache limited your activities for a day or more in the past 3 months? If you answered yes to two questions, you’ve just “ID’ed” your migraine. Your next move: Talk to your doctor about the best migraine meds. More from Prevention: Real Solutions For Migraine Misery
