It's a long story, but I was bitten extensively by a dog four weeks ago. Went to the ER, got the puncture wounds cleaned (didn't need stitches), and was prescribed an antibiotic. The scars and bruising have mostly gone away, but the place on the back of my thigh is still swollen and tender. Feels sort of lumpy. I reluctantly made an appointment with the doctor for Wednesday to get it checked out. I've not seen ANY red streaks in that area, but it seems like the swelling would have gone away by now. Can anyone give me an idea of how long it might take to heal? A friend suggested that the dog's tooth might have broken off in the wound.
