High temperature with abdominal pain
A high temperature (fever, 38°C or above) together with abdominal pain is a combination that is worth checking. It can be from a common stomach bug — but it can also be a sign of something that needs treatment, such as a urinary or kidney infection or appendicitis.
When to get medical help
Use NHS 111 online, call 111, or contact your GP if:
- Fever plus abdominal pain for more than 24 hours
- Pain that starts around the belly button and moves to the lower right — could be appendicitis
- Pain in the side or lower back with a fever — could be a kidney infection
- You are pregnant
- You have a long-term condition affecting your tummy
Call 999 or go to A&E if you have severe abdominal pain that is getting worse, a rigid tummy, vomiting blood, pain that stops you moving, or you feel faint.
