*looks around for strangers*
( i see a few
strange people but NO strangers!

)
As far as the Copaxone, I was on it for 1 1/2 years and I can tell you the Arnica gel really helped me. I kept the tube in the freezer, the gel doesn't freeze. It cooled the site after I did the shot, and reduced the welt and burn and itching that always seemed to hang around for days afterward.
I too found it hurt less and left less of a welt and itchiness when I injected manually. You get to control the speed of the injection and it was better injecting sloooowly for me.
As far as injection sites, I did R thigh, R hip, R stomach, L stomach, L hip, L thigh. I never did my arms because I didn't want anything showing.
Good luck and NEVER be afraid of us!
( or most of us anyway!!!
