Aww barb, I am so sorry. Perhaps its the mannitol. They have stabilizers and such to keep the drug stable until delivery. It can be more than just the amino acids in the Copaxone, but with that kind of reaction, i dont blame you for not wanting to do it again. Perhaps the next one should you chose to would be a witnessed injection. That way they can see what happens to you.
hugs, and prayers to you
