Possible causes of kidney pain include:
- Bleeding in your kidney (hemorrhage)
- Blood clots in kidney veins (renal vein thrombosis)
- Urinary tract infection
- Arteriosclerosis / atherosclerosis (hardening of the arteries leading to the kidneys)
- Horseshoe kidney, a condition present at birth in which the two kidneys are fused together
- Kidney cancer or kidney tumor
- Kidney infection (pyelonephritis)
- Kidney swelling due to a backup of urine (hydronephrosis)
- Polycystic kidney disease
However, it's possible to have one of these conditions and experience few symptoms, including kidney pain.
Kidney stones cause pain, but it's not referred to as kidney pain. Kidney stones generally are painless — or relatively painless — as long as they remain in the kidneys. It's when the stones move out of the kidneys that pain typically occurs — waves of sharp, intense pain, which doctors call renal colic or ureteral colic.
