In the early postoperative period after perianal abscess surgery, pain will definitely occur in the incision. Generally, there is no obvious pain for 10 days after surgery. At this time, the granulation begins to proliferate and grow, and the nerves inside the granulation will also begin to grow, so itching will occur, which is normal. Some patients have unhealthy growth of granulation and will have excessive secretion, which can stimulate the skin around the anus and cause itching. In some people, the anal canal is deeper and the local ventilation is not good, so the secretions will accumulate inside and more bacteria will multiply, which will also cause local itching. The amount of secretion is related to a person’s constitution. Some people have a weak spleen and dampness, and the meatus is easily edematous. With more secretions, you can use Chinese medicine, topical and oral to correct the heavier dampness according to the situation. And some people are allergic because of topical medication. After the allergy, it will also cause itching, and there will be obvious redness and swelling around the local skin, which requires timely discontinuation of the medication causing the allergy, and if necessary, anti-allergy medication.
