When my husband injected the back of my arm, a pain shot down my whole arm into my hand (like it had hit a nerve or something.) This happened at 8:15 in the morning and it is now 7:50 in the evening and 2 of my fingers and that side of my hand are still numb. Note that the terrible pain that I originally felt lasted a half but the numbness is still there. Note I never had numbness in my hand from MS itself - it definitely is related to the injected. This shooting pain down my arm into my hand happened once before about 2 months ago, but at that time, I was fine after anout 1/2 hour. I had been on copaxone over 6 years before this happened. has this happened to anyone else? Any thoughts?
