First, regulate defecation: keep the stool unobstructed to reduce the irritation of feces to abscess. Second, clean the anus: take a bath with warm salt water or potassium permanganate solution every day. A douche can be prepared for flushing after defecation. Third, it is necessary to hang the anus when doing it: the airtight anus will aggravate the infection. 4. Appropriate medication: oral antibiotics can be taken according to the doctor's advice to control inflammation. Anorectal specialized hospitals generally provide patients with anorectal rehabilitation packages, which include hand-held washcloths that are convenient for patients to wash their anus with water at any time, anal hydrotherapy devices that can be placed on the toilet for bathing, and painless breathable pads that can overhead the painful parts of the anus, so that patients can sit painlessly. But the price opened by the hospital is twice as expensive as that on Taobao.

Finally, I wish you a speedy recovery!
