The symptoms of anal fistula recurrence are similar to those of the original fistula, mainly painful swelling around the anus, pus and blood, itching and dampness around the anus, pus and blood flowing out when pressed, and a rope-like channel leading to the inside of the anus when felt, which shows the recurrence of anal fistula. The reason is that anal fistulas, especially the more complex ones, are longer and more branched, and some are even above the rectal ring of the anal canal, which is particularly deep. The actual fact is that you will be able to get a lot more than just a few of these.
