Hemorrhoidectomy, Fissureectomy & Sphincteroplasty

I had hemorrhoidectomy,fissurectomy & sphinteroplasty 6 weeks ago, where the doctor removed three packets of piles (at 3,6 and 11 o'clock). The fissure was remove at the pile at 6 o'clock and a sphinteroplasty was performed at 6 o'clock. I still get severe pain & bleedin at passing motion and the pain lasts for about two hours after passing motion. My doctor says the cuts are overhealing and keeps applying silver nitrate on a weekly basis. He has done this twice & will try once again next week. He says if the wound does not close, he will need perform another surgical procedure.

I am not sure if he has done something wrong & does not want to tell me. I am so stressed and do not want to undergo another surgery.

Before the surery I was not in such pain, now I have been in severe pain for 6 weeks and keep taking painkillers.

Please tell me your views.

Thanking you in anticipation
