Kidney stones do not always cause symptoms. Problems arise when the stone gets stuck or develops during an infection. Extreme, sharp pain in the side or lower back is the main sign of a kidney stone. It may come and go in waves or cycles, or spread to the groin or inner thigh. A stone can block the flow of urine, which can lead to swelling in the kidney.
Other common symptoms include:
Kidney, Ureter, Bladder, and Kidney Stone
