Appendicitis is a painful irritation of the appendix, which is a narrow, finger-shaped pouch attached to the large intestine in the lower right side of the abdomen. Appendicitis occurs when the inside of the appendix becomes filled with something that causes it to swell, such as mucus, stool or parasites.
