Burning when you pee with fever or pain under the ribs: do not wait

Tell the clinic or emergency desk: ‘I have pain when I urinate and now I have fever or shivering and pain here under my ribs.’ Point to the painful side and say when each symptom began. Mention vomiting, blood in urine, pregnancy, diabetes, kidney disease or a weakened immune system if relevant. The NHS lists fever, feeling shivery and pain under the ribs among reasons for urgent assessment when a urinary infection is suspected. You do not need to prove that the kidneys are involved before seeking help.

A burning feeling alone can have different causes, and back pain alone can too. It is the new combination and how unwell you feel that changes the urgency. Do not wait to see whether the fever settles after a night, and do not treat a remote questionnaire or video call as a substitute for someone assessing you in person. A clinician may examine you and decide which urine or other tests and treatment are needed.

Get immediate local emergency care if you become confused, very drowsy or have difficulty speaking. The NHS lists these as emergency signs in the context of a possible kidney infection. Also tell the receiving team if you cannot keep fluids down, have not passed urine all day or are becoming rapidly more unwell. NICE advises hospital assessment for signs of serious illness and considers extra risk when a person is pregnant, dehydrated or has underlying conditions.

If you have started prescribed treatment but symptoms worsen or do not begin to improve within 48 hours, seek reassessment rather than simply repeating the same medicine. NICE recommends reviewing for other diagnoses or complications in that situation. Bring any medicines you are taking and any previous urine-test result if you have one; do not start leftover antibiotics or change a prescription on your own.

If you are already arranging urgent care, a short note can help: the time fever started, temperature if measured, which side hurts, whether you have nausea or blood in urine, and any prior urinary symptoms. It should take less time than completing a full online guide. If transport is difficult, ask local emergency services or someone you trust for help reaching in-person care.

Our six-question urinary guide helps organise symptoms in non-emergency situations. It now shows an immediate in-person care message when fever, shivering or pain under the ribs is selected. It cannot diagnose a kidney infection, judge severity remotely or choose an antibiotic. For the warning signs above, go for care first.
