i just got a steroid nerve block shot yesterday, and at the pharmacy it was a different brand of percocets, that i dont usually get. anyway, sice last night ive been noticing my heart fluttering,and except feeling agitated, i dont feel as though ive taken any pain meds.my back hurts as though i have not taken anything, and i have a stiff neck this morning.does this sound like a side effect of the steroid injection, or the new percocet script.im thinking maybe the steroid injection is stopping the percocets from working, if this is the case, hopefully only for a short time.does anyone know anything about this, please respond?
