I asked my Nero how many lessions I had and he showed me my MRI ,he counted 15 with some in the back round fading. Does it me for every lession you have is relapes, I forgot to ask him that. Just had my first infussion med and I am doing good with no side efects. I wondered at my age going on 65 to soon, is it kind of late to start meds, will it help me? I have spascity in my legs and hip problems when I walk. I still work and plan to for at least another year and half. Anyone out there starting treatment late in life? It to the neros years to dx me.
