I am sort of fascinated that everywhere seems to say "we don't know why this happens" despite the fact that we also know that the place that anti-CGRPs are most likely to cause side effects is... the gastrointestinal system. Like??? surely "proposed CGRP signalling mechanism" ought to be at least being proposed?

-- ah, okay, turns out that if I poke academic literature rather than patient advocacy orgs, I start getting some mention of this. But only since around 2021, which I am mildly baffled by.

(I also need to actually hunt down more descriptions of What It Is Like and What The Hangover Is Like, because today I am much less photosensitive and the nausea's cleared off, too, but everything from the muscles on out in my general stomach Area is sore enough to be causing Difficulties. Did everything go into spasm and now I get the aftereffects of that? Did the Pain just make all of those nerves realise they could be constantly going AAAAAAAAAAH again? Is something else going on? I Have No Idea But I'm Bored. Default action of "throw painkillers at it" contraindicated by, you guessed it, migraine.)
