17 Signs That You Might Have Kidney Stones

1. Back and Flank Pain

The pain caused by kidney stones is called renal colic. It is a severe type of pain, and may be intense enough to lead to a visit to the emergency room. It is often triggered when a large stone becomes lodged in the urinary tract, but especially if it’s in the ureter. The ureter is the tube connecting the kidney to the bladder. Renal colic is most commonly felt in the back, as the kidneys are located against the muscles there. It may also be felt along the side of your body. The pain typically occurs in waves that may last between 20 and 60 minutes.
