I inherited migraines through paternal lineage, at least x2 generations back behind me. My personal deal has turned out to be overall environmentally triggered -- specific foods, specific smells, overwhelming tyrannical stress, a pinch of "still have to figure it out", and like this. Sometimes it got Real Bad, like "last night made me doubt that my physical brain matter can't directly feel pain even though I believe medical science" or "sleeping next to the toilet as though I were an end-stage alcoholic on a bender" type of Bad. Visual auras, trouble speaking and actually understanding native language as if intoxicated or suffering dementia, finger numbness, loss of fine motor control... all clear signs//symptoms for me. Thankfully I've been able to mitigate triggering variables for myself. Apparently my father has not; his situation is worse than mine and I hope this drug offers some options.
