Interstitial Nephritis

Interstitial nephritis is a kidney condition characterized by swelling in between the kidney tubules.The main functions of your kidneys are to filter your blood and to get rid of waste from your body. The kidney tubules reabsorb water and important organic substances from the filtered blood and secrete substances you don’t need into your urine for removal from your body. Swelling of these tubules can cause a number of kidney symptoms that range from mild to severe.
