What are the most common signs of appendicitis?

The early symptoms: Of appendicitis are abdominal pain that starts diffusely or around the bellybutton and then localizes to the right lower quadrant (rlq) of the abdomen; some nausea, maybe with vomiting; and decreased appetite (anorexia). Early signs of appendicitis are abdominal tenderness that ultimately localizes to the rlq; there is discomfort with movement (e.g., the bumps in the road cause pain).
