Introduction

Kidney pain is a common reason people seek medical attention, especially when it is severe, persistent, or associated with urinary symptoms. The kidneys are located on either side of the spine, just below the rib cage, and pain arising from these organs may indicate kidney stones, infections, urinary obstruction, or other kidney disorders.

Because kidney pain can sometimes be mistaken for muscle strain or back pain, understanding the kidney pain causes and symptoms is important for early diagnosis and treatment. Timely medical evaluation can help prevent complications and protect kidney function.

At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive kidney evaluations, advanced diagnostic testing, kidney stone management, chronic kidney disease care, dialysis guidance, and personalized treatment plans.

Where Is Kidney Pain Felt?

Kidney pain is usually felt in the flank area, which is the region between the upper abdomen and the back below the ribs.

Pain may occur:

On the right side
On the left side
On both sides
In the lower back near the kidneys
Radiating toward the lower abdomen or groin

Kidney pain is often deeper and more internal than ordinary back muscle pain.
