My mom has been suffering from chronic migranes since her youth but they have been getting more and more frequent with age. Now they come every month and they completely debilitate her. She can't eat, sleep, move, nothing. Whatever she does eat she immediately vomits. 

Her migrane is at the base of her skull where it connects to the neck and when I massage it for her, I can feel a lump there.

We've been to doctors, done all sorts of scans and the only meds that work for her Is this pill that she has to take before the migrane is in full swing. If she misses the window, it does nothing for her pain. 

I've tried massaging her, hot and cold pads, wrapping a scarf around her head. Nothing seems to ease the pain. She says she only feels some relief after vomiting for some reason.

I hate seeing her like this and feel so helpless. If anyone knows how I can make this more bearable for her I would be eternally grateful.

EDIT: I should have specified this above, we live in a third world country, and certain medical treatments that might be available in the West will not be available here or might be more risky. So, while they are appreciated, and I will most definitely look into all of them, suggestions of that nature will probably not be viable. 

I would appreciate some tips or tricks for dealing with the migraine once it comes. Ways to lessen the pain if possible.
