The presence of a mass around the anus along with pain should be considered a perianal abscess in most cases. In the early stage of abscess, that is, when the mass is first found, it may be hard to touch. As the inflammation becomes suppurative after 3-5 days, the mass may become softer to the touch and even have a fluctuating sensation, or even some of the masses may break down and pus may flow out, while some patients may also have an increase in body temperature. Most of these cases are caused by perianal abscesses, which need to be treated in the hospital, and can be incised and drained to reduce the symptoms, and then after the inflammation subsides, anal fistulotomy can be performed, or one-time radical surgery for perianal abscesses can be performed directly.
