i do copaxone too but havn't had the problems you do.
i can understand why not feeling well on a daily basis wears you down.

try to hold til your mri report.
would you consider tysabri? really works well for some.

i had A LOT of local side effects when i first started C. with time they abated.
i also experimented with the depth setting of my autoject and found when i went deeper that those effects got much better.

icing also helped me.
it's a daily reminder of MS but for me it was worth it not to have interferon side effects.

post here and we'll get you thru this.
hang tight.
