Kidney discomfort — also referred to as renal discomfort — refers to discomfort from ailment or harm to a kidney. You may well really feel kidney discomfort or soreness as a boring, 1-sided ache in your upper stomach, side or back. But discomfort in these locations is typically unrelated to your kidneys.

Your kidneys are positioned in the back of your stomach beneath your lower ribs, 1 on every side of your spine. People typically are surprised at how large their kidneys are. Most circumstances that bring about kidney discomfort affect only 1 kidney. Fever and urinary symptoms typically accompany kidney discomfort.
