I've been on rebif since january and i cant say that i have had that happen. The only thing with me is when i inject on my affected side i get a spasm Its like my leg jerks really bad when the medicine goes in. It bothers me really bad. I try to avoid the left leg. MS life lines said you dont have to inject in every site allowed so i avoid it. I hope it settles for you. How long have you been on it? Maybe its a reaction that will settle after a while? I rarely get side effects anymore thank goodness. Good Luck.
Dx Dec 06, Rebif,44mcgs 3 x wk, Baclofen
