What is flank pain?

Pain that is felt on your side and back just below the rib cage is referred to as flank pain. Flank pain can be caused by an obstruction of the flow of urine from the kidney to the bladder. This is most commonly caused by kidney stones and infection, but may be associated with other conditions.


Evaluation of flank pain will involve an urine analysis, urine culture, and imaging studies such as a CT scan and an ultrasound.


Treatment is based on the cause of the flank pain.
