Appendicitis can be tricky to diagnose unless you have the typical symptoms.
However, around one in two people with appendicitis do not have typical symptoms.
Moreover, some people's appendix may be located in a slightly different part of their body, such as the pelvis, behind the large intestine or behind the liver.
Some people develop pain similar to appendicitis, but it's caused by something else, like a bladder or urine infection, Crohn's disease or gastritis.
A doctor will ask about your symptoms, examine your abdomen and see if the pain gets worse when pressure is applied to the appendix area (the lower right-hand side).
