Appendicitis is a painful swelling of the appendix, a finger-like pouch connected to the large intestine. Appendicitis typically starts with a pain in the middle of your abdomen (tummy) that may come and go. Within hours the pain travels to the lower right-hand side, where the appendix usually lies, and becomes constant and severe. Pressing on this area, coughing or walking, may all make the pain worse. You may lose your appetite, feel sick and occasionally experience diarrhoea.
