Thanks to everybody giving me advice on tysabri. Very nervous because I am JC virus positive although my doctor swears I'm still safe because it's a low number but I'm very nervous. Is anybody else in the same boat as me? I have a since 1989 but I wasn't diagnosed will 2014 I'm still independent and I don't use any assistance but things are progressing which is why I'm switching therapies and hoping for the best. Good to meet you all
