Just threw up and nearly passed out from a migraine. I know it’s a migraine because I get them once or twice a year. But what ACTUALLY causes them?

Some evidence suggests that migraines happen when the blood vessels between the skull and the brain press on nerve fibers. That’s why medications that affect blood pressure (like beta blockers) can help treat migraines.
