Migraine

I am working on a case for a friend of mine - i know i should't, i am not finished yet with study, but i'ld like to help...
she's got bad migraine. comes on every time, the weather changes to cold. or on thunderstorms. She thinks, it's the barometric pressure, that causes it.
The headache starts in left eye and then moves up and back, so the upper left quarter of head is affected. she has to close the eye or hold a hand in front of it. she can't have light or noise and has to lie in a dark quiet room. The headache never goes away, unless she is able to fall asleep. which she can't unless she is taking so much painkiller, that she is pretty much 'knocked out". the eye hurts as if a iron-rod would be forced into it. she pinches her gums underneath the eye (upper yaw) when she has the headache. she thinks it's the same nerve that goes through the eye and the teeth and when she pinches her gums she says the pain kind of moves away from the eye to the teeth. Therefore she was even thinking of getting the teeth up there extracted !! Sometimes she has to vomit on an attack.
The pain starting from the eye moving direction 'back of the head" puzzles me a little. i find tons of remedies that have the pain moving the other way. with her it really starts IN the eye.
I was thinking of Phos and Spig. Phos seems to suit the case pretty well, but is more related to thunderstorm and not to weather change? Spig was the first i was thinking of, but i don't like that the pain moves from back to fron and THEN goes to the eye.
Any other idea?

I am thinking to find something palliative, for the time being. she has lots of other symptoms like bad back, talks and never stops, doesn't wait for other people to answer etc. I know, migraine is chronic and to cure it, i really had to work the case out, but i am ot ready to do this. yet.

what do you think about phos and spig?
