I have a sore on my stomach that started out as a small red bump and in the past 2 weeks has turned purple, peeled back, and started bleeding and oozing pus. I am worried only because it has been here so long and because it is very tender to touch. It now is a small hole that is open and it seems to be getting a little larger but is still very small. What could this be and what are good treatments for it?
It looks like a fistulous or sinus tract in your abdominal wall. So it is basically treated by sinus tractarsupialisation with normal granulation tissue. Go for a surgeon and sonography with tract exploration.
