It is normal to have abdominal pain after appendicitis surgery, but the patient should be closely monitored for signs of peritonitis and the presence of a laminar abdomen. If there are no signs of peritonitis, you can treat the symptoms with pain relief. There are traditional open surgery and minimally invasive laparoscopic surgery, but no matter which surgery is performed, there will be incisions in the abdominal wall, and the incisions in the abdominal wall can damage the dermal nerves in the abdominal wall, which can lead to painful incisions after surgery. The placement of drains can also cause pain at the drains, which can be treated with painkillers. In addition, although the appendix is removed during appendicitis surgery, the inflammation around the appendix is not completely treated, and it can still spread to the abdominal cavity, causing pain and discomfort in the abdominal cavity. Therefore, the patient’s signs should be closely observed, and if the abdomen is soft on pressure, symptomatic treatment with pain relief injections is also available.
