Well, my next Tysabri infusion was scheduled for this Wed April 6th, I cancelled it and scheduled with my neurologist. So, I see him on Wed instead of having the infusion.

I have had a lot of negative side effects since the infusion too, the most uncomfortable and scarey is that my heart feels like it is beating out of my chest.....and now that my JC Virus test is positive, I want to discuss what other options I have at this point.

Thanks everyone.....I really appreciate all of your comments. It is nice to hear what someone else would do in the same situation.

I am afraid to do nothing, as I had 5 additional brain lesions in a 9 month period....but truly I don't see using one of the ABC-R. The effectiveness is just not enough, considering that they have found out now that the interferons only work for 50% of MS patients. I think placebo effect was pretty close to the actual effectiveness of the ABC-R's.
