I can honestly say that if it were not for tysabri I would have no Idea what I would have done. I have been on tysabri since april and I can say I feel like I did before I was diagnosed. The only symptoms I ever had was a headache right after my first infusion. PML was and still is my greatest fear but I think the quality of life I had prior to tysabri is worth the risk to me. I make sure I keep my Gastro imformed of any changes and go from there. Hope This Helps
