It's wonderful to meet you and please make yourself at home here! Itching, along with redness and lumps can be common side effects to Copaxone. Usually these kind of side effects go away on their own, but if it becomes intolerable or you develop something like hives make sure you contact your doctor.
There are a few things you could try. If you haven't called Shared Solutions already it might be worth a try to make sure you doing everything correctly. If you are using an autoinjector sometimes the depth needs to be adjusted depending on the place and the person. Try icing the injection site before and after to see if that reduces the itching and redness. Heat might also work if the ice doesn't. An anti-itch ointment might help since your itching seems to be a prolonged issue and if over the counter stuff doesn't work, you could ask your doctor about a stronger prescription version.
A couple of other suggestions is to inject at room temperature. I usually take it out of the refrigerator about 15 minutes prior to injection. And, make sure the alcohol on the skin is completely dry before you inject.
Best of luck, and I hope your itching resolves soon! Please let us know how things go.
