Can a UTI cause back pain and fever?
Yes, a UTI can cause back pain and fever, especially if the infection has reached the kidneys (pyelonephritis), which requires prompt medical treatment.
Detailed Medical Explanation
UTIs that progress to the kidneys (upper urinary tract infection or pyelonephritis) can cause symptoms like high fever, chills, and pain in the lower back or side. These symptoms are a sign of a more serious infection that can lead to complications if untreated. Immediate medical care is recommended. NHS: UTI and kidney infection.
Clinical Context
Clinics treat UTIs early to prevent progression to kidney infection. Any back pain or fever with urinary symptoms warrants urgent review.
Evidence-Based Approaches
NHS and NICE urge immediate assessment for UTI with back pain or fever. Antibiotics and sometimes hospital care are needed for pyelonephritis.
