from my understanding, you only get the Severe reaction if you inject into a vein. As the copaxone is meant to be injected subcutaneously, I would assume by the massive bruise I had the next day, that it hit a vein. I have not (fingers crossed) had another one since, and October 7th will be my one year anniversary for being on Copaxone
I've had one relapse (in June) but it is much better than the 4 or 5 I was experiencing prior to going on the Copaxone therapy, so I must say I am pretty happy with it all in all.
