I would check with the doctor.
I get itchy at the site and stay itchy for a few days.
I use the tucks after which help me.
Benydrl cream also works.
I never get itchy where I haven't injected.
Better to be safe than sorry.
Good luck.
With in the first few weeks of Copaxone you can get itchy or develop welts this is normal. This is your body saying hey my body does not produce this stuff. I think it was my eighth injection where all my sites blew up like peaches. It does not happen to everyone. You can take an oral antihistimine if you tolerate them and use benadryl cream or spray. It should get better if not call your Doctor. As far as stinging at the site after injection everyone is different mine was always like that so I did my injections while watching TV so I could think about something else.

I've read that itchiness can be a big side effect of Copaxone. I just have occasional itchiness at the injection site, but not all over. My SS nurse told me that some people find relief by using a Tucks wipe after injecting instead of a cotton ball. I tried that and it didn't really help me. I started using it in February and the burning and itching seems to be getting better for me. It sounds like your reaction is much worse than mine! Good Luck!!
