A ruptured appendix may lead to... Peritonitis: inflammation of the parietal and visceral peritoneum. Peritonitis may be localized or generalized, and may result from infection or from a non-infectious process. The main manifestations of peritonitis are acute abdominal pain, abdominal tenderness, and abdominal guarding, which are exacerbated by moving the peritoneum, e.g. coughing (forced cough may be used as a test), flexing one's hips. Pressure over McBurney's point in the RLQ will cause maximum pain and rebound tenderness Abdominal guarding is the tensing of the abdominal wall muscles to guard inflamed organs within the abdomen from the pain of pressure upon them. The tensing is detected when the abdomen wall is pressed.
