Welcome to the board. I'm sorry you're having a tough time finding a disease modifying medication that you can tolerate. I've been on copaxpone for a long time. I have experienced lipoatrophy as well. I have a couple "dents" from copaxone. I try to inject in my stomach and hips most of the time. I avoid thighs and arms due to those being the places that show more.
Have you called and asked shared solutions about this? Perhaps making an adjustment to depth may help.
I too, am not a fan of medications that may cause PML. Before you rule out all meds, you may want to see if you happen to be negative for the JC virus. That reduces your chance for PML quite a lot.
Best of luck. Keep us posted.
