My first flare (2003) lasted about three months...both of my legs were numb. It resolved itself before I could be dx. My next flare (about two years later in 2005) lasted about five months. I had double vision, L'Hermitts, Bells Palsy, dizziness, numbness and tremors. I have permanent nerve damage from that flare. My right hand and arm is numb. My Neuro says it's permanent. I have regained some use of it back...or trained myself to use it.

I don't know how they determine when you've gone SP from RR. I think it's when you see just a steady decline with no recovery but I could be mistaken.

It's a tricky disease with no two people the same. I can see why it's so hard to dx if you don't have obvious lesions or your LP comes back normal.

I feel fortunate to have gotten back what little use I have of my right hand and arm. There for a while it was completely useless and that's a scary feeling.
