On another site, MSW, I remember reading something about this but don't remember the details. You could probably do a search there and come up with a few threads. Others have experienced something similar to what you have been experiencing. Sadly, since I never noticed a difference, I really didn't pay much attention to that thread.

You could always call the pharmacy where you get your medicines. I get mine from Curascript and they have always been helpful. Although, my brother trained many MSers how to inject and trained me as well. Any issues that I had I usually talked to him about.

Hang in there and hopefully other Copaxoners will chime in with some advice.

BTW - Thanks for this thread as it is another reminder to me to pay attention to what my body is saying. I still have trouble doing that. LOL
