Copaxone shot gone wrong!

Was due today for my right arm shot of my Copaxone, and after four and a half years I was bound to get a nerve sooner or later, and it feels as if I did!
I am writing lefty and I am no lefty!
This is it for this evening and thanks for understanding, but my right arm is both numb and in pain, and yes both can happen and to me it does way too often...
