Hi there and good morning - are u using the auto injector? Are u sure that you are rotating properly and not injecting in approx the same spot each time. Sometimes with me, I will take my shot and there is absolutely nothing at all, then out of the blue I take a shot and it causes me some problems for a couple of days afterwards.
As noted here in the other posts, likely one of the best people to help u is the Copaxone nurse who has been assigned to u for support...
