Pain in the kidney region usually refers to discomfort felt in the side of the body, the back or the area below the ribs where the kidneys are located.

However, pain in this region does not always mean that the kidneys are the source of the problem.

Muscles, the spine, nerves, ribs and abdominal organs can also cause discomfort in the same general area.

When the pain is caused by a kidney or urinary problem, it may be associated with symptoms such as changes in urine, fever, nausea, blood in the urine or difficulty passing urine.

Identifying the actual cause is important because treatment for muscle pain is very different from treatment for a kidney stone, kidney infection or urinary obstruction.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides specialist evaluation for patients with kidney-function concerns and suspected kidney-related conditions.

Where Is Kidney Pain Usually Felt?

The kidneys are located toward the back of the upper abdomen, on either side of the spine and below the rib cage.

Kidney-related pain may be felt:

• In the flank or side of the body

• In the back below the ribs

• On one side or both sides

• Moving toward the abdomen

• Radiating toward the lower abdomen or groin in some stone-related cases

The exact location and pattern of pain can provide useful clues, but pain location alone cannot confirm a kidney problem.

What Are the Common Causes of Pain in the Kidney Region?

Several kidney and non-kidney conditions can cause pain in this area.

Kidney Stones

Kidney stones can cause severe pain when they move into the urinary tract or obstruct the flow of urine.

The pain may:

• Begin suddenly

• Become severe

• Come in waves

• Move toward the lower abdomen or groin

Other symptoms can include:

• Blood in the urine

• Nausea

• Vomiting

• Burning during urination

• Frequent urination

A stone that causes obstruction may require medical evaluation and, in selected cases, a procedure.

Kidney Infection

A kidney infection can cause pain in the side or back and may be associated with:

• Fever

• Chills

• Burning urination

• Frequent urination

• Nausea

• Vomiting

• Feeling generally unwell

Kidney infections require prompt medical assessment because untreated infection can become serious.

Urinary Obstruction

Urine flow may be blocked because of conditions such as:

• Kidney stones

• Ureteral narrowing

• Enlarged prostate

• Structural abnormalities

• Other urinary tract conditions

Obstruction can cause pressure to build up inside the urinary system.

Persistent obstruction may affect kidney function.

Kidney Cysts

Some kidney cysts do not cause symptoms.

However, larger, complicated or infected cysts may occasionally cause discomfort or pain.

Imaging helps determine whether a cyst requires further evaluation.

Kidney Inflammation

Certain inflammatory or immune-related kidney diseases may affect kidney function.

These conditions do not always cause pain, but some patients may experience flank discomfort or other symptoms.

Additional findings such as protein or blood in the urine may help guide evaluation.

Can Pain in the Kidney Region Be Caused by Something Other Than the Kidneys?

Yes.

Many conditions can cause pain near the kidneys without directly affecting kidney function.

Examples include:

• Muscle strain

• Back problems

• Spine conditions

• Rib injuries

• Nerve irritation

• Digestive conditions

• Other abdominal or pelvic conditions

This is why persistent pain should not automatically be treated as kidney pain without appropriate evaluation.

How Can Kidney Pain Be Different From Muscle or Back Pain?

The pattern of pain may provide useful clues.

Kidney-related pain may be more likely to occur with:

• Blood in the urine

• Burning during urination

• Frequent urination

• Fever or chills

• Nausea or vomiting

• Reduced urine output

• Severe colicky pain

Muscle pain may become worse with certain movements, lifting, bending or changes in posture.

However, symptoms can overlap, and a medical examination may be necessary to identify the cause.

Pain in the Kidney Region on One Side

Pain may occur on either the left or right side.

Possible causes include:

• A stone affecting one kidney or ureter

• A kidney infection

• Urinary obstruction

• Muscle or spine problems

• Other conditions affecting nearby structures

One-sided pain does not automatically indicate a kidney disease.

Imaging and urine testing may be required when kidney involvement is suspected.

Pain in the Kidney Region on Both Sides

Pain affecting both sides may have several possible causes.

Possible explanations can include:

• Muscle strain

• Back or spinal conditions

• Bilateral urinary tract problems

• Certain systemic illnesses

• Other medical conditions

Because the kidneys themselves are located on both sides, bilateral pain may raise concern for a urinary or kidney-related problem, but the cause cannot be confirmed based on pain alone.

Can Kidney Disease Cause Pain?

Many chronic kidney diseases do not cause pain during the early stages.

A person may have reduced kidney function, protein in the urine or elevated creatinine without experiencing flank pain.

Pain may occur when a kidney condition is associated with:

• Stones

• Infection

• Obstruction

• Swelling of the urinary system

• Certain cystic conditions

• Other complications

Regular kidney testing can therefore be important even in people who have no pain.

What Tests Can Identify the Cause of Kidney Region Pain?

The doctor may recommend tests depending on the symptoms.

Urine Examination

Urine testing may help detect:

• Blood

• Protein

• Infection

• Other abnormalities

Blood Tests

Blood tests may include:

• Creatinine

• eGFR

• Electrolytes

• Blood count

These tests can help assess kidney function and identify other medical concerns.

Ultrasound

An ultrasound may help identify:

• Kidney stones

• Urinary obstruction

• Kidney swelling

• Cysts

• Structural abnormalities

CT Scan

A CT scan may be recommended when detailed evaluation is needed, particularly when a kidney stone or another urinary condition is suspected.

What Is the Treatment for Pain in the Kidney Region?

Treatment depends on the underlying cause.

If a Kidney Stone Is Responsible

Treatment may involve:

• Appropriate pain management

• Observation in selected cases

• Medical expulsive therapy for selected ureteric stones

• Shock wave treatment

• Ureteroscopy with laser treatment

• Other procedures when clinically necessary

The best option depends on the size and location of the stone.

If an Infection Is Responsible

A bacterial kidney infection may require appropriate antimicrobial treatment.

The choice of treatment depends on the severity of illness, urine findings and other clinical factors.

If There Is Urinary Obstruction

The priority may be to restore normal urine drainage.

The appropriate treatment depends on the cause and severity of the blockage.

If the Pain Is Not Kidney-Related

Treatment will depend on the actual cause, such as a muscle, spine or other medical condition.

Can Drinking More Water Help Kidney Region Pain?

Drinking excessive amounts of water is not a universal treatment for kidney pain.

Appropriate hydration may be helpful in some situations, particularly when dehydration is present.

However, excessive fluid intake may be harmful for people with:

• Advanced kidney disease

• Heart conditions

• Significant fluid retention

• Certain urinary obstructions

Fluid intake should be individualized.

Should You Take Pain Medicine for Kidney Pain?

Pain medicines may be used depending on the cause of the pain and the patient's medical condition.

However, some pain medicines can affect kidney function in susceptible individuals.

People with kidney disease or reduced kidney function should not self-medicate without discussing appropriate options with a healthcare professional.

The priority is to identify the cause rather than repeatedly suppressing severe or recurring pain.

When Is Pain in the Kidney Region an Emergency?

Seek urgent medical attention if pain is accompanied by:

• Fever or chills

• Severe or rapidly worsening pain

• Persistent vomiting

• Very little or no urine

• Blood in the urine with severe symptoms

• Severe weakness

• Confusion

• Breathlessness

• Rapid deterioration in health

A combination of urinary obstruction and infection can be particularly serious and requires prompt assessment.

When Should You See a Nephrologist?

A nephrologist may be helpful when kidney region pain is associated with:

• Elevated creatinine

• Reduced eGFR

• Protein in the urine

• Blood in the urine

• Recurrent kidney stones

• Repeated urinary infections

• Suspected chronic kidney disease

• Unexplained kidney-function changes

Certain structural urinary conditions or stone procedures may also require evaluation and treatment by an appropriate urological specialist.
