If you have a fistula, it is not from the anus, but from the fistula. The main manifestation of anal fistula is an external opening around the anus, like a pimple, and an internal opening inside the rectum, with a tube between the internal and external openings called a fistula. Patients with fistulas need surgery, and it usually takes about a month and a half for the wound to heal completely after surgery. If the fistula is high and complex, it usually takes about two months for the wound to heal after surgery. The actual fact is that you will be able to get a lot more than just a couple of hours of time to get a lot more than just a couple of hours of time. In the first half month after the surgery, the wound pain is obvious and the perianal discharge is especially high, which are normal. As the wound gradually heals, the above symptoms will gradually improve.
