Can a UTI Cause Back Pain?
Yes, a UTI can cause back pain when the infection spreads to the kidneys. Lower urinary tract infections typically cause bladder symptoms like burning and frequent urination, but when bacteria travel upward to the kidneys, it creates pyelonephritis. This kidney infection causes flank pain in the lower back, often on one side. Studies show that up to 30% of untreated UTIs can progress to kidney involvement. The back pain is usually accompanied by fever, chills, nausea, and severe urinary symptoms. Kidney infections require immediate medical attention as they can lead to serious complications including sepsis.
