Dog bite

This is probably illegal as hell but I gotta try. I was involved in a pitbull fight Friday morning and on top of being bit in several places I was bit right on the head of the dealio. They gave me a shot and antibiotics but every time I have to flush it out it's excruciating. I called and asked for pain meds and they said sorry feel better. I'm not offering trade or money just expending my options for something besides OTC and bacitracin.
