My close friend suffers from migraines and occasionally she will lose control of her senses as a result(i.e. hearing things that aren't there) and will have her blood vessels explode and constrict, causing pain.

 

She gets the more mild type of migrains too, but this subtype really has me baffled mainly because I've never heard of it before. Her doctor said it's "rare but not unheard of", so maybe someone around here knows about it? Thanks.

It causes me agony and impairs my vision, and it totally blinds my mom, so you have our empathy, but I'm not sure what triggers what reactions.

mild hallucinations associated with migraines are usually called migraine auras or visual migraine aura hallucinations. They are quite common. if you google for "migraine aura" or "migraine hallucination" there should be a lot of info out there.

OK thanks, I'll look into that. And yeah, AzurePhoenix, it's a real hassle to live with (so she has said).
