Lately my migraines have been lasting 3-4 days. They are not responding at all to abortive medications, just lots of quiet time and days off from work. This started happening about 3 months ago (I' had migraine for 1.5 years). I had an MRI with contrast 1.5 years ago and it was normal, but now I'm wondering if I should get another one. My neurologist says he doesn't think so, but maybe just for my own piece of mind?
