Kidney Pain: Causes, Symptoms When to See a Doctor
Kidney pain is not just back pain—it’s a specific type of discomfort that can be a sign of serious underlying health issues. Knowing how to identify kidney pain and understanding what causes it can help you act quickly and protect your kidney health.
In this blog post, we’ll explore what kidney pain feels like, its possible causes, associated symptoms, and when to seek professional help.
What Is Kidney Pain?
Your kidneys are bean-shaped organs located on either side of your spine, just below the rib cage. Kidney pain usually occurs in the flank area, which is the side of your back, just below the ribs. It can be felt on one or both sides and may radiate to the lower abdomen or groin.
Kidney pain is different from general back pain—it often indicates a problem within the urinary system and should not be ignored.
Common Causes of Kidney Pain
1. Kidney Stones
One of the most common causes, kidney stones are hard mineral deposits that form in the kidneys. They can cause intense, sharp pain when they move or block the urinary tract.
Symptoms may include:
Severe pain on one side of the back
Nausea and vomiting
Blood in urine
Painful urination
2. Kidney Infection (Pyelonephritis)
A kidney infection is usually caused by bacteria traveling from the bladder. It can cause serious complications if left untreated.
Symptoms may include:
Dull, aching pain on one or both sides
Fever and chills
Frequent, painful urination
Cloudy or foul-smelling urine
3. Polycystic Kidney Disease (PKD)
An inherited disorder where fluid-filled cysts develop in the kidneys, causing pain and kidney dysfunction over time.
Symptoms may include:
Persistent pain or heaviness in the back or sides
High blood pressure
Blood in the urine
Enlarged abdomen
4. Urinary Tract Obstruction
Blockage in the urinary system—such as from a tumor, enlarged prostate, or scar tissue—can lead to pressure buildup and kidney pain.
5. Kidney Injury or Trauma
A direct blow or accident affecting the kidneys can result in pain, bruising, or internal bleeding.
