Already I have asked a question before, still I have some doubts, could you pls help me doctor. One and a half month ago I had a laser fissure surgery, now I have anus problem, pus is formed at (laser incision) I had a surgical site infection. Small amount of pus is draining out of my anus. I went to my surgeon who operated me, he examined me, he said that no pus is there, still I have a problem with pus, doctor suggested me ofloxacin, again he said there is a chances of fistula formation. What is the solution if fistula is formed. Could you pls tell me symptoms of fistula, pls suggest me ointment and tablets.
