Injection in arm causes numbness in hand

[JR1176]

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?

The arm is my tough spot to inject and I recently called SS about this problem.  I would do the shot and I would have pain in my wrist and in my shoulder joint. But only on my right arm - never my left.  

They had me adjust the setting to a lower number and that has made all the difference. When I checked, my autoinjector was at a ten - they had me take it back to a 6. It was immediately a better experience.

SS also sent me a new autoinjector- yours might need to be replaced too (if you use one!)

Be sure to talk to your neuro and SS about this problem.  
best, Lulu

It sounds like he hit a nerve going in.  Maybe the radial?  I would see if the numbness goes away, and talk to your neurologist if it doesn't.

I don't know about you, but I've had problems with that nerve.  Sometimes I'll extend my arm and an electric shock shoots down my arm.
