Ann, I've never had this done, but it doesn't sound too unusual to me. After rereading the above posts, with my limited medical knowledge, I feel both doctors are on the right track. You can read forever about diagnosing MS, but the bottom line is you have to go with a neurologist who is familiar with the local machines, labs, personnel in the area. Typically, these days, MRI lesions and patient history can diagnose it. If there is a question with these, there are other tests (oligoclonal bands in the spinal fluid, various evoked potentials, etc.). There is just too much variability with all these to even venture a guess...that's why you choose the best doctor you can find and trust him/her. The MS Society is a wonderful resource to maintain contact with.

Whatever the tests to come, Amy needs your support now. I'll be in touch.
