An appendix is a small, finger-shaped pouch that projects from the large intestine. It is located in the lower right quadrant of the abdomen. The appendix has no known function, and its removal does not appear to have any adverse effects. However, the appendix can become inflamed, a condition known as appendicitis. Appendicitis is a common cause of abdominal pain, and it can be life-threatening if not treated promptly.
There are a number of ways to check your appendix. One common method is to palpate the abdomen. This involves feeling the abdomen with your hands to identify any areas of tenderness or pain. If you have appendicitis, you may experience pain in the lower right quadrant of your abdomen. This pain may be worse when you cough or move around.
