Fistula should be operated as there is no other way out for this problem. Basically, it’s a zit developed somewhere on the body mainly near anus and rectum area. Zit gets compacted and then the skin starts getting putrefying from that area, further it when it bursts, yellow pus starts erupting out of it. Moreover, this pus should not be deliberately stopped otherwise it starts infusing inside the body which could be poisonous. Fistula can’t be cured by any medication rather operating is the best and simple way to get rid of it. If anyone is suffering from piles, they can take P-care medicine for two months to cure it.
