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.
Abdominal pain. Appendicitis usually involves a gradual onset of dull, cramping, or aching pain throughout the abdomen. As the appendix becomes more swollen and inflamed, it will irritate the lining of the abdominal wall, known as the peritoneum. This causes localized, sharp pain in the right lower part of the abdomen. The pain tends to be more constant and severe than the dull, aching pain that occurs when symptoms start. However, some people may have an appendix that lies behind the colon. Appendicitis that occurs in these people can cause lower back pain or pelvic pain. Mild fever. Appendicitis usually causes a fever between 99Â°F (37.2Â°C) and 100.5Â°F (38Â°C). You may also have the chills. If your appendix bursts, the resulting infection could cause your fever to rise.
