Introduction
Back and flank pain is a common symptom that may occur due to muscle problems, spinal conditions, or disorders affecting the kidneys and urinary system. The flank area is located on the sides of the body between the ribs and hips, where the kidneys are located. Because kidney-related conditions can sometimes cause pain in this region, it is important to identify the underlying cause.
While many cases of back pain are related to muscles or bones, persistent flank pain associated with urinary symptoms, fever, blood in urine, or abnormal kidney function tests may indicate a kidney problem requiring medical evaluation.
At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive kidney evaluations, advanced diagnostic testing, personalized treatment plans, kidney stone management, dialysis planning, kidney transplant evaluation, and long-term kidney care.
