Copaxone question

So hubby is only newly diagnosed the past few months & he's is using the Copaxone injections...He is always left with lumps on the injection site afterwards..His MS nurse & Copaxone nurse say it's normal & it will settle but surely it should have in the 5 months he has been using it??.He tried an ice pack,heat pack & cream to prevent it but nothing works..He is starting to get very self conscious about it..

Has anyone else been through this?? If so do you have any tips?? It will be greatly appreciated
