I spent most of my life thinking "migraine" was just a really bad headache. Until I started getting migraines. The best way to describe it is a band of white hot pain, almost a stabbing sensation. It started behind the eyes and would spread everywhere. Not confined to my head, a full-on nervous system meltdown: extreme light sensitivity, blurred vision, trouble with balance and coordination, nausea, numbness, and residual effects that lasted over a day. With a migraine, there is no "take an advil and power through" - you sit in a dark room and pray.
