Hi! I don't mean to speak badly of your Vet. Some wounds are real hard to call. But in the future, he should use an I&D and not a pressure bandage. What happened was the abcess had no where to drain. If he had made an incision, and inserted a few inches of gauze and left a piece out to drain, the infection would have followed that path. What happened, was the pressure bandage caused the abcess to move under the skin, build up in intensity and ate thorough the flesh. It literally exploded. Tell me all the other things you have tried so I don't waste your time and mind with a repeat. Then I will try to help you.
