Does kidney pain come and go?

Yes, kidney pain can come and go, especially with kidney stones where it often appears as sharp, cramping waves (renal colic) that fluctuate as the stone moves, but it can also be a constant dull ache, particularly with infections, and usually doesn't change with movement like muscular back pain. The intermittent nature is often due to the body's contractions trying to pass the stone through the narrow ureter.

How do I know if my pain is from my kidney?

You know your pain might be kidney-related if it's a deep ache high on your back/side (flank), below the ribs, often on one side, accompanied by fever, nausea, vomiting, painful/frequent urination, or changes in urine (blood, cloudiness). Unlike muscle back pain, kidney pain is usually constant, deep, and doesn't improve much with movement or rest, often signaling an infection or kidney stone. 

Why does my kidney pain come and go?

Kidney pain often comes and goes in waves (colic) because it's usually caused by a kidney stone moving and causing spasms in the ureter as the body tries to pass it, with pain subsiding when the ureter relaxes or the stone shifts. Other intermittent causes include a kidney infection (pyelonephritis) or conditions like polycystic kidney disease (PKD) where cysts might burst or swell, causing acute pain that can fluctuate, while dull aches might signal chronic issues like enlarged kidneys. 

What is often mistaken for kidney pain?
