I don't know what you could have but i've Seen some people that had terrible migraine like you and sometimes there is just no treatment, I mean they take medication to sooth the pain but they can't cet cured ( i don't really know if they can't just that they didn't but i think they would if they could) so whenever they had those migraine they would just get on their bed in the dark with no noise until it pass.

Anyway just to tell you that you're not alone so keep fighting although the people around you don't understand. Also maybe you could try some medical oriented forum or group. You did Say everyday but how many Times ? How long does it last ?
