Sudden and severe pain
Adults are often diagnosed with kidney stones after a trip to the emergency room or visit to their primary physician because of sudden severe abdominal and/or back pain they’ve been experiencing. This sudden and severe pain in the stomach and/or one side of the back is one of the classic symptoms of kidney stones.
“Pain associated with kidney stones often comes on suddenly and is sometimes described as excruciating as the pain associated with labour,” says Douglas Propp, MD, Medical Director and Chair of Emergency Medicine at Advocate Lutheran General Hospital in Park Ridge, Illinois.
Severe pain from which you can find no relief helps differentiate pain associated with kidney stones from a stomach ache or back strain. Pain associated with kidney stones can sometimes be confused with a backache because pain associated with kidney stones can start higher up in the back. As the stone moves closer to the bladder, the location of the pain can move lower. An important difference though: The back pain that accompanies kidney stones is unlike the pain of typical back strains because it is not associated with any movement.
“One can usually figure out which side the kidney stone is on because the pain will typically, although not always, be on one side of the stomach versus the other,” says Dr. Coogan.
Kidney stones can range in size; Dr. Coogan notes the average size of a kidney stone is 5 millimetres. However, the size of the stone doesn’t necessarily affect how much pain someone is in. Even a very tiny kidney stone can cause a “whole lot of hurt,” says Dr. Coogan. Kidney stones can be so painful that they awaken people from sleep and prevent them from finding a standing, sitting, or lying down position that provides relief.
“The pain can come on at any time and is severe, typically preventing the individual from finding a comfortable position, says Dr. Propp.
