Mike: I am about 1 1/2 months out of my first year campath infusions(the 5 in a row). I knew I would drop out if I was randomized to rebif, and was then going to try tysabri. I felt very lucky and privileged to have been randomized to campath.
I have similar symptoms to yours. Don't know yet if it will do me any good, but I tolerated the treatment amazingly well, and am ready for the long haul!
Can you get tysabri, and have you considered it? It seems to be a good option.
Otherwise, if you can afford to go off-label, and can get it, I don't know if it will do any good, but don't be scared. I am an RN, and have to say, it was a peice of cake for me!
