A perianal abscess is an inflammation inside the anus that turns into pus, causing a lump to protrude next to the anus, often with symptoms of redness, swelling, pain and generalized fever. Perianal abscesses are mainly caused by long-term constipation, diarrhea and a spicy diet. There are often three forms of treatment for perianal abscess: First, if the early stage is not suppurated, anti-inflammatory treatment with antibiotics can be used, but this is rarely used, because perianal abscesses develop quickly, 1, 2 days or even less can be suppurated, when the patient begins to care may have been suppurated, with antibiotics, it is impossible to relieve. Second, some use the therapy of incision and drainage to drain the pus, this therapy is only temporary relief, not solving the root cause, because the root cause of pus is not dealt with, the possibility of recurrence is great, and the recurrence may be more serious. Third, Chinese medicine is to find the root cause of the infection and then eradicate it at once, which can cure it completely and the removed area will not recur. If it is a high abscess, Chinese medicine often uses hanging thread therapy. Hanging thread therapy is a characteristic of Chinese medicine and can effectively prevent the possibility of loss of anal function caused by surgery.
