Oh man! That's never fun.
Hopefully you waited at least 3 months between shots.
I'm not sure what causes your symptoms but try and remember to hold yourself in a neutral posture at all times. By keeping your head, neck, and shoulders where they're suppose to be you can significantly minimize symptoms and damage.
I have degenerative discs - the space between my c5 & c5 is gone and bone on bone now. So all of this isn't going to do anything.
