Last week I started my 3rd significant relapse this year, my specialist nurse is now talking about
Tysabri. I was on Rebif for about 15 months and wasnt getting on with the side effects so I switched to Copaxone 6 weeks ago, which I'm quite happy with.
I looked up Tysabri when I got home and all I got was all the bad news about the PML patients. They say that theres a 1/1000 chance of getting it, that seems quite high to me.
