If people are experiencing kidney pain, it can indicate a problem with one or both of their kidneys.
There are many reasons that people may have kidney pain, including:
A UTI: If bacteria affect part of the urinary tract, including the urethra or bladder, a person can develop a UTI. They don’t seek treatment for the UTI, and the infection spreads to the kidneys.
Kidney infection: It can affect both kidneys and be painful. Doctors call this condition pyelonephritis.
Renal vein thrombosis is a rare disease wherein a blood clot lodges in one vein that takes blood from the kidneys. Symptoms can appear suddenly or gradually.
Kidney cancer: Cancer forms in the kidneys if the cells begin to develop abnormally. Many cancers can harm the kidneys of both children and adults.
