I;'ve being using the shot for a year now, my back pain is just killing me, does anybody has the same thing, could it be the shot that is doing it or something else? i dont have insurance so i just start thinking it was the shot giving me this pain, but i also heard it was effects of the epidural, can somebody please help me, no mention how much weight i gain, i was 130 pounds right now i am 185 pounds, i am enormous.
