Kitty, i'm JC+ for a couple years & continue Tysabri BUT- JC level came back less then .5 which isn't very high. Lady in MS support group's level was over 3 & continues Ty. What's your level? My Dr said over 1 is risky, my call if it rises.

Tecfidera worked just about as good as Ty on me, I switched back to Ty after a few months of Tec cause MS was progressing but it's still progressing on Ty. At least I get to flirt with nurses & chat with chemo patients while getting Ty.
