It's Migraine Day again today. Not as bad as it was a couple of weeks ago. I have started a calendar to get some hard information on what my headaches are doing.
One thing that trips me up is that many of my headaches seem like sinus headaches in some ways, but migraines in others. I hate to take sumatriptan if it's not a migraine, because then I would get to deal with the muzzy feeling for the rest of the day (and still have the headache). But in the literature, an awful lot of people think they have sinus headaches when they actually have migraine syndrome. Guess I'll break down and take a sumatriptan in another half an hour (tried ibuprofen at 7:15, acetaminophen at 10:30).
Here's one abstract on a double-blind study of sinus versus migraine headache. And here's another.
