After appendicitis surgery, there are usually no more painful symptoms because after appendicitis surgery, the inflammation is relieved, so the symptoms are naturally relieved. If you still have pain after one month, there are two possible reasons: one reason is that there are adhesions in the abdominal cavity due to the inflammation of the abdominal cavity caused by the previous appendicitis, and the adhesions will pull the intestinal canal and cause pain; another reason is that there are postoperative complications, such as appendiceal stump infection, portal phlebitis and abdominal abscess after appendectomy. In this case, an ultrasound or CT examination of the abdomen, combined with routine blood results, is needed to further clarify the postoperative situation. If there are no infectious complications such as postoperative portal phlebitis or abdominal abscess, and only mild abdominal adhesions, the symptoms should resolve on their own after a period of time.
