I haven't had too many problems with the copaxone. I do have some welts and some bruising but never multiple days in a row. But I do not use the auto injector. I never liked the thought of that thing. If you can brave it, and it really isn't bad at all, you may want to try manual inject. It really works quite well for me. I just inject all the way in, which I guess would be the deepest level on the auto injector, and I usually don't have a problem. Maybe you could have someone manual inject it for you and just see and then you can decide whether to go to the manual technique. Good luck and hang in there. It does get easier.
