The pain felt during appendicitis is not like any pain one experiences during indigestion or a usual stomach ache. It starts near the belly button and moves lower to the right. Appendicitis occurs most commonly in people between the ages of 10 and 30, but it may happen to anyone at any given point in time. One out of 15 people develop appendicitis in his or her lifetime. The occurrence is highest among males, aged 10 to 14, and among females, aged 15 to 19. You will find that appendicitis leads to more emergency abdominal surgeries than any other condition.
