Appendicitis is a painful swelling and infection of the appendix. The appendix is a small appendage which is attached to the beginning of the large intestine or the colon. Person can easily find the appendix in the lower right portion of your abdomen. The most common symptom for appendicitis is the pain that is felt in the abdomen. This pain usually starts in the navel and then gradually shifts to the right of the abdomen. It is usually very difficult to track and identify the exact location of pain when it is moving. Symptoms of appendicitis include fever, nausea, vomiting, chills, loss of appetite, and pain on being touched on the lower side of the abdomen.

Causes for appendicitis include one or more of these two factors: a difficulty within the appendix, an abnormal change in tissue accompanied by the death of cells within appendix and the attack of bacteria. Appendicitis usually occurs after an digestive tract infection, or when the tube connecting the large intestine and appendix is blocked by trapped feces or food.
