I was told 2 years ago that I had optic nuritis, then I was told that I had MS because when I had the Brain MRI it showed 2 big lesions and a hole lot of little ones all over, now 2 years later my neurology doctor is questioning it, I went for a 2nd opinion and all the test came back negative yet I have all this lesions in my brain and no one seems to know why. So now I am asking for a 3rd opinion, I was told to stop the avonex shots and now i feel as bad as I did before the injections, when I was on the injections I felt great. What could this brain lesions be? I also suffer from migrain headaches and have headaches everyday/
