I think I know how a prodrome can start a day or two before rain or wind or weather fronts arrive. Early changes in barometric pressure could trigger it. But how on earth does my head know three or four days in advance when the predicted changes are still on the other side of the country? Case in point: We have rain and a cold front arriving tonight, so I have a migraine today. And I had prodrome symptoms yesterday — and the day before, and the day before that, and the day before that. It’s Thursday and I’ve had a variety of symptoms all week! Do our neurological systems have a secret connection to the National Weather Service? Do we have super-sensitive barometers in our heads that can pick up the tiniest shifts of isobar toward each other? Are we migraineurs “blessed” with weather-prediction capabilities that NWS, FEMA, NASA and the military envy? If so, they can have it!
Meanwhile, after almost 70 years of chronic daily migraine, I would love to know HOW I apparently know about weather triggers so far in advance. Any ideas?
