Because the specific conditions of the affected area are different, the time needed for healing is also different, such as the location, size and depth of the abscess, so there is no fixed time for healing, as short as 7~10 days, and as long as 1~2 months. 1. Smaller pus bags: for the formation of superficial soft tissue, the volume of small pus bags, after incision and drainage, the internal pus and necrotic tissue is completely removed, the newborn granulation tissue from the bottom of the gradual healing, the time is relatively short, usually about 7 to 10 days to heal. 2. Larger abscesses: For larger abscesses, especially those in deeper locations, the healing time will be slower, such as high perianal abscesses. Because the newborn granulation tissue needs to grow from the bottom of the abscess cavity, it often takes 1~2 months to heal completely. There are also some special cases, such as patients with malnutrition and chronic diseases such as diabetes mellitus, the healing speed is even slower. It is recommended that the patient go to the hospital and complete all auxiliary tests in order to clarify the condition.
