Pain around your kidneys can also be caused by other problems, such as: 1  problems with your spine or ribs. 2  muscle pain. 3  pneumonia. 4  a problem with your spleen or your liver. 5  a hernia.
The most common causes of CKD do not cause any pain. And, much of the pain that is near the kidneys is not caused by a kidney problem. But some people who have CKD do have pain. Some people with kidney problems may have pain in the upper back (where the kidneys are) or on the same side as the affected kidney.
