The reasons why it still hurts after appendicitis surgery are as follows: 1. The patient has an incision in the surgery, and there will be pain at the incision after the anesthesia fails after the surgery. If it is an ordinary open surgery, the incision is relatively large, and the incision will be a bit more painful; if it is a minimally invasive surgery, the incision is relatively small, and the pain is not so intense. 2. Although the patient has had the diseased appendix removed after appendicitis surgery, if the patient has septicemia around the appendix before it is removed, after the appendix is cut off, there is still a small amount of inflammation above the appendix stump, and the inflammation stimulates the intestinal wall or there will be pain. Therefore, postoperative anti-inflammatory injections are usually needed, and the pain will improve after the inflammation is relieved.
