A couple weeks later, I was at my parents' house, having consumed a wonderful meal, capped off with oreo ice cream. I began to feel a little dizzy. Then the pain. Then the nausea, which, this time resulted in vomit splattering all over--ALL OVER--their bathroom. I still don't know how I achieved that kind of blast radius. The remainder of the evening saw me lying helpless in an easy chair, where I spent the night. The next day all was well. A little hazy, but fine.
Since then, I've had blood work and an MRI (with and without contrast!). I don't fret one second about the results of the tests, which are forthcoming. But I do live in abject, absolute fear that the headache will return. The Doctor called them "Cluster Headaches." (Options two and three were Tumor and Slow Leaking Aneurysm, listed in order of likelihood.)
I don't care what it is. It might even be, as illustrious artist/poet J. Sadler has hypothesized, "Genius Headaches." Whatever it is, curses be upon it. May it never recur.
