Full Question:I have suffered from Migraines for about 15 yrs now, however, in the last month or more I have had about 7 episodes where I have part vision loss and then the really bad pain hits. I have had a MRI done in the last week and half which came back normal. What could this be? I have had my eyes checked, and nothing there either. I have been in a lot of pain everyday for a month now and its really getting me concerned. Any help would be appreciated. Thank you, Terri.
