I am back, a little more then a year after my post. I had another MS attack around July '09 and I have since switched to Tysabri. With tysabri, all of my symptoms, (tingling, numbness, and pain) are all but gone. For me, Tysabri was more effective then Copaxone, but if you have MS and are thinking of switching, Tysabri is a very dangerous drug, inform yourself before making the decision.
