You know, when I read about ON, that was the first thing I thought of... the auras I had and a potential link to ON (maybe I had ON long, long ago!).

I really should get my eyes checked, even if my neuro thinks I don't have ON, and told me the auras are migraine.

I can imagine lesion from migraine mimicking MS. I did have the positive spinal tap as well for o-bands. Of course, those o-bands can show up in other conditions as well.
