The post-operative incisional pain after cesarean section usually improves gradually in 1-2 days, and most patients can be completely relieved in about 7-10 days, but a very small number of pain-sensitive patients may still feel slight pain 1-2 months after the operation. The duration of post-operative incisional pain after cesarean section is related to the direction of the incision, personal fatness, physical fitness, and high or low pain threshold. Usually, the pain level is the worst within 24 hours after surgery, and the pain usually gets better within 24-48 hours. If the patient has a higher pain threshold and tolerates pain better, he may no longer feel pain 2-3 days after surgery. In addition, because the longitudinal incision is slightly more traumatic than the transverse incision, the pain may take about 7-10 days. If a woman has too much abdominal fat or does not take care of the incision after the cesarean section and the abdominal incision becomes liquefied or infected, the pain time will be significantly longer and may be about 1-2 months. Therefore, once the incision becomes infected, hematoma and other abnormalities after cesarean section, it should be treated accordingly.
