I think that's why I've always been too chicken to do my arm!! I used to use my arms when I was on betaferon, but it hurt too much so I stopped. And as copax jabs sting so much I've never been brave enough to try my arm again. Do you think that will be your first and last time??

I haven't injected into my arms, just my legs and stomach. I 've found I'm getting less of a reaction each time, but I am getting a twitching thigh muscle in my right leg when I inject there. It does sting a bit though, feels a little like my leg muscles have cramped up too
