Appendicitis often starts with a pain in the middle of your tummy that may come and go.
Within hours, the pain travels to your lower right-hand side. This is where your appendix usually lies. The pain can become constant and severe.
Pressing on this area, coughing or walking may all make the pain worse.
If you have appendicitis, you may also have other symptoms, including:
- feeling sick (nausea)
- being sick
- loss of appetite
- a high temperature (fever) and a flushed face
When to get medical help
If you're experiencing tummy pain that's gradually getting worse, contact your GP immediately. Any condition that causes constant severe tummy pain needs urgent medical attention.
You can confuse appendicitis with something else, such as:
- gastroenteritis (stomach infection)
- severe irritable bowel syndrome (IBS)
- bladder or urine infections
- Crohn's disease
- pelvic infection
If your appendix bursts, it can cause peritonitis. This is a serious infection of the inner lining of the tummy (abdomen).
