I was diagnosed in 1998 after optic neuritis in my right eye and 3 thoracic spinal lesions. The only new lesion I got in the next 14 years was in my cervical spine. I was doing great on my avonex until my Neuro said he wasn't going to give me, because I had devic's not MS. (long story short) So I went to see the head of DUKE neuro who told me I didn't have MS, though I should get MRI's every year. My brain was clear until 2011 when I got 10 lesions and my Dr. put me on Tysabri. So 14 years later I HAVE MS. I think every one is different and so are a lot of the Neurologist. Hang in there and find a Dr. you trust.
I thought I was crazy for years...
