Your body has two kidneys. Each kidney lies at the back of the body between your lower ribs and hips. The human kidneys are in the shape of beans. The size of each kidney is equal to the size of a fist.
Your kidneys are responsible for filtering the waste out of your body. They produce urine and remove the extra fluid and waste from your body.
What is kidney pain?
Kidney pain is not common. It indicates that something is wrong with your kidney and may happen with one or both kidneys.
