I never had any site reactions with my Copaxone shots. Maybe it just isn't for you?
My friend here was on C for 3 yrs and she looked like a pock marked, puffed up, pin cushion. Her Doc finally took pity and took her off of it.
None of the DMDs are great enough to keep suffering the side effects, IMHO!
Stick with it...yes...but if the sx don't ease up soon, then it's time for a change..
