Signs and symptoms of appendicitis may include: 1  Sudden pain that begins on the right side of the lower abdomen. 2  Sudden pain that begins around your navel and often shifts to your lower right abdomen. 3  Pain that worsens if you cough, walk or make other jarring movements.  Nausea and vomiting.
The first symptom of appendicitis is usually nausea, then pain or a vague, uncomfortable feeling around the navel. Things often go downhill rapidly from there. In acute appendicitis, intense pain builds in the lower right side of the abdomen. Many people also experience a loss of appetite (anorexia), vomiting, a feeling of tenderness in the abdomen, or a slight fever. In some people, the appendix sticks out in an unusual place or an odd angle. In these cases, appendicitis can cause other symptoms such as pain in the sides or the back, pain during urination, or pain in the upper left side of the abdomen. If you have these symptoms, go to an emergency room immediately. Appendicitis is a medical emergency.
