Renal colic

Renal colic is a type of pain commonly caused by kidney stones.The pain typically begins in the kidney area or below it and radiates through the flank until it reaches the bladder. The pain is colicky in nature, meaning that it comes on in spasmodic waves as opposed to being a steady continuous pain. It may come in two varieties: dull and acute; the acute variation is particularly unpleasant and has been described as one of the strongest pain sensations felt by humans.[1]
