Migraine?

Ordinarily, I don't get headaches. I think that I could count on one hand the number of headaches I have had my whole life. Today, I got a migraine. My vision blurred and I felt very odd. For a bit I was kind of scared something was seriously wrong with me. I was hot and then cold and all the while my vision was getting more and more blurred. After about 45 minutes the pain had set in. It wasn't incredibly painful, but it was uncomfortable.
