Kidney Pain

Kidney pain is generally felt in the back. The feeling is often noticed in the upper back. It is not frequently dull or aching, but rather tends to come in waves that are sharp and sometimes severe.

Symptoms such as a dull pain in the middle or lower area of the back may instead be signs of issues related to the muscles, ligaments, disks, or other parts of the body.


While kidney pain causes may vary from one case to another, some potential underlying medical causes may include the following conditions and situations:

Angiomyolipoma (benign neoplasm)
Bleeding of this organ
Blocked urine flow
Kidney stones
Loss of blood supply to it (blockage of its artery)
Polycystic kidney disease (PKD)
Post streptococcal glomerulonephritis
Pyelonephritis (infections)
Renal (kidney) cancer
Renal tuberculosis (TB)
Simple kidney cysts
Urinary tract infections

Some possible causes of kidney pain are more serious than others. If concerned about discomfort in the region, please see a professional for assistance in diagnosis of the actual body part being affected, as well as the medical cause behind the sensation.


Diagnosis of an underlying condition behind kidney pain may be given by a doctor or medical professional. As the conditions are different, separate tests, examinations, and other methods may be used in order to attempt to discover a medical problem that is leading to the discomfort. Do understand that the medical causes listed on this website are not the only possible reasons.


Kidney pain treatment may vary greatly based upon the medical condition that requires treatment. Please seek a particular diagnosis prior to attempting to resolve a supposed problem, which may not actually be the issue at hand.
