When to get medical help
If you have abdominal pain that's gradually getting worse, contact your GP or local out-of-hours service immediately.
If these options are not available, call NHS 111 for advice.
Appendicitis can easily be confused with something else, such as:
- severe irritable bowel syndrome (IBS)
- bladder or urine infections
- Crohn's disease
- a pelvic infection
But any condition that causes constant abdominal pain requires urgent medical attention.
Call 999 to ask for an ambulance if you have pain that suddenly gets worse and spreads across your abdomen, or if your pain temporarily improves before getting worse again.
If your pain eases for a while but then gets worse, your appendix may have burst.
A burst appendix can cause peritonitis, which is a serious infection of the inner lining of the abdomen.
