Stomach pain with fever but no diarrhoea: what to know

Fever suggests the immune system is responding to infection or inflammation, although the cause may be outside the bowel. Pain can occur with a urinary infection, gallbladder problem, stomach inflammation or an abdominal condition that begins before other symptoms appear. The absence of diarrhoea does not rule these out. Pay attention to whether pain settles in one area, becomes worse with movement, or comes with vomiting, urinary changes, cough, sore throat, rash or unusual vaginal symptoms.

Rest, drink small amounts regularly and check your temperature with a reliable thermometer. Eat lightly if hungry and avoid alcohol. Follow the label for fever relief, checking first with a pharmacist if you have liver, kidney or stomach disease, take blood thinners, or are pregnant. Do not use leftover antibiotics. Note the fever pattern, pain location, vomiting, urine changes and medicines so a clinician can assess the full picture.

Seek emergency care for severe or rapidly worsening pain, a hard or very tender abdomen, confusion, collapse, breathing difficulty, blood in vomit or stool, repeated vomiting, or inability to keep fluids down. Arrange same-day assessment for persistent fever, pain settling in the lower right abdomen, yellow skin or eyes, painful urination, or marked weakness. Children, older adults and people with reduced immunity may need earlier advice.

Ask what causes should be considered from the pain's location and examination. Mention recent travel, sick contacts, surgery, pregnancy possibility, urinary or respiratory symptoms, and medicines. Ask whether urine, blood or imaging tests are needed and when to return if the fever continues.
