I used to get migraines that would stretch out for days. After trying so many things (without luck), I went to a dermatologist  about my skin lesions that i have had since they first appeared when i was 7 years old. I was diagnosed with a form of  Celiac disease called Dermatitis herpetiformis, also known as DH and Duhring's disease. With in ten days of  removing all gluten out of my diet, my migraines practically disappeared. I would definitely suggest getting food allergy tested for my fellow migraine sufferers.
