Hello, I just got my second surgery, I had a perianal abscess and after two weeks Ive developed a new one, just on the opposite side. My first wound was starting to heal, looked pink-ish just like normal flesh would. Now that I got my second surgery I’ve noticed that my old wound looks completely different and looks like its covered with something yellowish. What might that yellow be? I just left hospital and didn’t notice before, the yellow thing is on the new wound as well. Could it be some cream or something that they put in the wound? Im confused...
