(I think I am one of the big Avonex cheerleaders)
I don't know that Avonex
did make me feel better. I just know my change has been amazing since I began the injections. I can drive, I have more energy, I think clearly, my balance is better, I can walk farther, I have almost no problems with tingling or numbness. It may simply be a good remission but it has occurred as I took Avonex. I would really hate to have to quit.
Some of these changes could be psychosomatic; my neurologist thinks very highly of Avonex and assured me from the beginning I would be pleased. So you could say I went into it with positive thoughts. Another thing is I only know one other person on Avonex and he has had NO SYMPTOMS in the 5 years he has used it.
Just my opinion, but you asked!!
