The fact that there is still a little edema after 24 days of circumcision is mainly considered to be related to factors such as incision damage, poor prognosis and bacterial infection. 1. incision damage: the patient circumcision by external damage, or in the recovery stage pulling the circumcision, can lead to incision damage, and then the symptoms of edema. 2. Poor prognosis: during the recovery period, not doing a good job of dietary care, often eat spicy and stimulating food, or not regularly to the hospital to change the drugs, re-bandage, will affect the recovery of the incision, and even cause edema and other symptoms. 3. Germs infection: The affected area is infected by germs after surgery, which will cause inflammatory reaction, resulting in edema and congestion of the affected area, which in turn will affect the postoperative recovery. After 24 days of circumcision, the symptom of edema at the incision must be taken seriously, consult a doctor in time, and dispose of it under the doctor’s guidance.
