Bindsanator that sounds like MS, not rebif. I had paralysis, sudden onset, with MS. Another MS'er friend who has never taken any DMD's has had a few bouts of her leg just freezing, then it resolving quickly.
I know you're saying you don't want to take anything that harms your skin (neither did I but rock and a hard place and all that!) but I suppose you have to weigh up levels of risk and benefit. I 'failed' on Rebif - MS got worse - but have done really well on Copaxone with no loss of mobility but with other non-visible symptoms and relapses. My legs have lipoatrophy (Copaxone is subcutaneous- like Rebif, and I did develop 2 small patches of lipo on Rebif) , they look awful - but I can walk as far as I want, go for a cycle sometimes even.
Did you contact your neuro when the paralysis happened?
