Symptoms of Kidney stones

Stones may cause no symptoms, but if a stone becomes stuck in a ureter (one of a pair of tubes carrying urine from the kidney to the bladder), the muscle of the ureter wall goes into spasm (ureteric colic). This is reckoned to be one of the worst pains anyone can experience. The pain may spread to the lower abdomen and into the groin (referred pain). Blood in the urine is a common sign of kidney stones.
