How common is fever in urinary tract infection?

A urinary tract infection can affect the bladder or the kidneys. Bladder infection may cause burning when passing urine, a frequent or urgent need to urinate, and lower abdominal discomfort. Fever, chills, pain in the side or back, nausea, or vomiting can suggest that infection has reached the upper urinary tract and needs prompt assessment.

Fever alone does not establish a urinary tract infection. A clinician may ask about urinary symptoms, examine you, and request a urine sample. Other illnesses can cause fever, and some urinary infections occur without it.

Seek medical advice for fever with urinary symptoms, especially if you have side or back pain, feel shivery, or are vomiting. Drink normally if you can, but do not force fluids when vomiting or if a clinician has given you fluid restrictions. Use fever relief according to the label and your personal medical advice.

If antibiotics are prescribed, take them as directed and do not use old or shared medicine. Arrange review if symptoms fail to improve, return after treatment, or become more intense.

Get urgent medical help for fever with severe side or back pain, repeated vomiting, confusion, fainting, marked weakness, or difficulty passing urine. Pregnancy, childhood, older age, kidney problems, or a weakened immune system can make prompt assessment especially important.

Could this infection involve my kidneys? Do I need a urine test or culture? Which pain or fever medicine is safe for me, and when should I seek a review if symptoms continue?
