been there done that! whoever gave you the shot hit a nerve. the burning is when the nerve "miss-fires". it's pretty much gonna hurt for a long long time. this is just what happened to me when i couldn't use my right arm for three months. i hope everything turns out o. k.
why does my shoulder still hurt 3 months after a tdap vaccine? is there anything i can do to stop the burning pain? . ibuprofen 800mg tid does not help.
