Migraines

My grandmother and sister have been plagued with migraines as long as I can remember. I have never had them...or least I thought I had never had them...until recently. In fact, a couple of years ago I was having this weird flashing wavy light thing happening in my eyes and I thought I was having eye problems. Well, my eyes were fine. I finally realized I was having a precursor to a migraine, although not severe migraines. Today, I'm sitting here at my desk and there it goes again. I thought I might not be able to drive home mainly because I couldn't see very well. I took an Advil and continued to work at my desk and then realized that the flashing wavy lines were gone, but wait, now there is tightness in my head and it begins.
