I'm so sorry you're in so much pain
I've never had a migraine but I've had some REALLY bad headaches..I wanted to cry but it hurt too much. I can't imagine hurting more than that and for two whole days. I hope you can find something that works. I've seen Marcia Cross talk about her migraines and something that worked for her...maybe she has a website with info on it tht you could look up.
