Experiencing pain in both kidney areas can be concerning, particularly when the discomfort is felt on both sides of the back below the ribs. However, pain in this region does not always mean that both kidneys are affected.
Muscle strain, spinal problems, urinary tract conditions, kidney stones, infections, obstruction, and several other conditions can produce discomfort in the flank or back. Some kidney diseases, including chronic kidney disease, may cause few or no symptoms in their early stages.
Understanding the location and nature of the pain, along with associated symptoms, can help doctors determine whether the kidneys are involved.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, a super specialist nephrologist, provides comprehensive kidney evaluations, kidney-function testing, diagnostic assessment, and individualized treatment for patients with kidney-related symptoms.
Where Are the Kidneys Located?
The kidneys are located toward the back of the abdomen, on either side of the spine and below the lower ribs.
Pain associated with the kidneys may be felt:
-
On the right or left side below the ribs
-
In the flank
-
Toward the back
-
Sometimes toward the abdomen
-
Toward the groin in some cases, particularly with kidney stones
Kidney-related discomfort is often described as deeper than ordinary muscle pain.
However, pain location alone cannot confirm that the kidneys are responsible.
Does Pain in Both Kidney Areas Mean Both Kidneys Are Diseased?
Not necessarily.
Pain on both sides may occur because of a kidney condition affecting both kidneys, but it can also arise from muscles, joints, nerves, or the spine.
Possible explanations include:
-
Kidney infections
-
Kidney stones affecting both sides
-
Urinary obstruction
-
Hydronephrosis
-
Polycystic kidney disease
-
Certain inflammatory kidney disorders
-
Muscle strain
-
Spinal conditions
-
Nerve irritation
A proper medical assessment is important when pain persists or is accompanied by other symptoms.
Common Kidney-Related Causes of Pain in Both Kidney Areas
Kidney Infections
A kidney infection, or pyelonephritis, can cause pain in one or both flanks.
Symptoms may include:
-
Fever
-
Chills
-
Flank or back pain
-
Burning while urinating
-
Frequent urination
-
Nausea
-
Vomiting
-
Cloudy or foul-smelling urine
A suspected kidney infection requires prompt medical evaluation.
Kidney Stones
Kidney stones can cause severe pain when they move into the urinary tract.
If stones affect both kidneys or urinary tracts, discomfort may occur on both sides.
Possible symptoms include:
-
Severe flank pain
-
Pain that comes in waves
-
Pain extending toward the abdomen or groin
-
Blood in the urine
-
Nausea
-
Vomiting
-
Burning during urination
-
Difficulty passing urine
A stone does not have to affect both kidneys for pain to be felt in different areas.
Hydronephrosis
Hydronephrosis occurs when urine cannot drain normally from a kidney and backs up into the collecting system.
When both kidneys are affected, bilateral hydronephrosis may occur.
Possible causes include:
-
Kidney stones
-
Ureteral narrowing
-
Urinary tract obstruction
-
Bladder outlet obstruction
-
Certain structural abnormalities
Significant obstruction can threaten kidney function and requires appropriate evaluation.
Polycystic Kidney Disease
People with polycystic kidney disease can develop enlarged kidneys and cysts.
This may cause:
-
Aching flank or back discomfort
-
Abdominal fullness
-
Blood in the urine
-
High blood pressure
The condition requires long-term nephrology monitoring.
Other Kidney Disorders
Certain inflammatory or structural kidney conditions can occasionally produce flank discomfort.
However, it is important to remember that many forms of chronic kidney disease do not cause pain, especially during the early stages.
Non-Kidney Causes of Pain in Both Sides of the Back
Pain in both kidney areas is frequently caused by problems outside the kidneys.
Muscle Strain
Heavy lifting, exercise, prolonged sitting, poor posture, or sudden movements can strain the back muscles.
Muscle-related pain may:
-
Worsen with movement
-
Improve with rest
-
Be tender when touched
-
Follow physical activity
Spinal Problems
Problems involving the spine or discs can cause pain across one or both sides of the lower back.
Depending on the condition, pain may travel into the hips or legs.
Nerve Irritation
Nerve compression or irritation can cause:
-
Burning pain
-
Tingling
-
Shooting pain
-
Pain extending into the buttocks or legs
Joint or Soft-Tissue Problems
Problems involving the spinal joints, pelvis, or surrounding tissues can also cause pain in the same general region as the kidneys.
Because the kidneys are located near several muscles and structures, the source of pain can be difficult to identify without examination.
How to Tell Kidney Pain From Back Pain
There can be considerable overlap, but certain features can provide clues.
Kidney-Related Pain May:
-
Feel deep inside the body
-
Occur below the ribs or in the flank
-
Occur with urinary symptoms
-
Be accompanied by fever or chills during infection
-
Cause nausea or vomiting
-
Radiate toward the abdomen or groin with some stones
Muscle or Spinal Pain May:
-
Change with movement or posture
-
Improve with rest
-
Be tender to touch
-
Follow physical activity or injury
-
Occur without urinary symptoms
These characteristics are not enough for self-diagnosis. Persistent or severe pain should be medically evaluated.
Symptoms That May Occur Along With Bilateral Kidney-Area Pain
Pay attention to other symptoms that occur with the pain.
These may include:
-
Fever
-
Chills
-
Burning urination
-
Frequent urination
-
Blood in the urine
-
Foamy urine
-
Cloudy urine
-
Reduced urine output
-
Difficulty passing urine
-
Nausea
-
Vomiting
-
Swelling of the feet or face
-
High blood pressure
-
Persistent fatigue
The combination of symptoms can help determine which investigations are appropriate.
When Is Pain in Both Kidney Areas an Emergency?
Seek urgent medical attention if pain occurs with:
-
High fever or chills
-
Severe or rapidly worsening pain
-
Persistent vomiting
-
Difficulty passing urine
-
Very low or absent urine output
-
Severe weakness
-
Confusion
-
Significant swelling
-
Known urinary obstruction
Particular caution is needed when a urinary blockage is accompanied by infection. An infected obstructed urinary system can become a medical emergency and may require urgent drainage.
Do not attempt to manage severe obstruction or infection only with home remedies.
How Is Pain in Both Kidney Areas Diagnosed?
The diagnostic approach depends on the symptoms and medical history.
Medical History
A nephrologist may ask about:
-
Location of the pain
-
Duration
-
Severity
-
Whether the pain is constant or comes in waves
-
Urinary symptoms
-
Fever or chills
-
Previous kidney stones
-
Previous urinary infections
-
Existing kidney disease
-
Current medications
-
Diabetes
-
Blood pressure problems
Blood Tests
Depending on the situation, investigations may include:
-
Serum creatinine
-
eGFR
-
Blood urea nitrogen
-
Electrolytes
-
Complete blood count
-
Blood glucose
These tests help assess kidney function and identify infection or other abnormalities.
Urine Tests
Urine testing may include:
-
Routine urinalysis
-
Urine microscopy
-
Urine culture
-
Protein or albumin assessment
These tests can identify blood, infection, protein leakage, and other abnormalities.
Imaging
Depending on the suspected cause, doctors may recommend:
-
Kidney ultrasound
-
Non-contrast CT scan
-
Other imaging when clinically indicated
Imaging can identify stones, hydronephrosis, obstruction, cysts, and structural abnormalities.
Treatment for Pain in Both Kidney Areas
Treatment depends entirely on the underlying cause.
Kidney Infection
Kidney infections generally require appropriate antibiotic treatment.
The choice and duration of treatment depend on:
-
Severity of infection
-
Urine culture results
-
Kidney function
-
Other medical conditions
Severe infections may require hospital-based treatment.
Kidney Stones
Small uncomplicated stones may sometimes pass naturally with appropriate medical management.
Treatment may include:
-
Pain control
-
Medicines for selected ureteral stones
-
Appropriate fluid intake
-
Follow-up imaging
If a stone causes persistent obstruction or fails to pass, active removal may be considered.
Possible procedures include:
-
ESWL
-
Ureteroscopy with laser lithotripsy
-
RIRS
-
PCNL for selected larger or complex stones
A urologist generally performs stone-removal procedures, while a nephrologist can assess kidney function, metabolic stone risk, and prevention strategies.
Hydronephrosis or Urinary Obstruction
When pain is caused by obstruction, treatment focuses on restoring urine drainage and addressing the underlying cause.
Depending on the situation, management may involve:
-
Treatment of a kidney stone
-
Ureteral stent
-
Nephrostomy drainage
-
Treatment of bladder outlet obstruction
-
Other urological procedures
The appropriate intervention depends on the cause and severity.
Muscle or Spinal Pain
If kidney disease is excluded and the pain is musculoskeletal, treatment may involve:
-
Appropriate rest
-
Physical therapy
-
Posture correction
-
Exercise or stretching when appropriate
-
Medical pain management
People with kidney disease should consult their doctor before using painkillers because certain medicines can worsen kidney function.
Can You Treat Bilateral Kidney-Area Pain at Home?
Home care depends on the cause.
For mild pain clearly associated with muscle strain, conservative measures may sometimes help.
However, kidney-related symptoms should not be treated solely at home when there is:
-
Fever
-
Blood in the urine
-
Severe pain
-
Persistent vomiting
-
Difficulty passing urine
-
Reduced urine output
-
Known kidney disease
-
Suspected urinary obstruction
Avoid excessive water intake as a self-treatment if obstruction is suspected.
Avoid unverified herbal or “kidney cleansing” remedies.

Frequently Asked Questions
Does pain in both kidney areas mean both kidneys are damaged?
No. Pain on both sides can result from kidney conditions, but muscle strain, spinal problems, and nerve-related conditions can also cause bilateral back or flank pain.
Can kidney stones cause pain on both sides?
Yes. Stones can affect both urinary tracts, although bilateral stone disease is not the only explanation for pain on both sides.
Can kidney infection cause pain in both kidneys?
A kidney infection can affect one or both kidneys. Fever, chills, urinary discomfort, nausea, or vomiting occurring with flank pain should prompt medical evaluation.
Does chronic kidney disease cause pain?
Many forms of chronic kidney disease do not cause pain in the early stages. Pain is more commonly associated with conditions such as stones, infections, obstruction, or certain cystic kidney disorders.
Should I drink more water for kidney-area pain?
Not automatically. Fluid requirements depend on the underlying condition. Excessive water intake can be inappropriate or harmful in certain situations, including significant obstruction, advanced kidney disease, or fluid overload.
When should I see a nephrologist?
Consult a nephrologist if the pain persists or is accompanied by high creatinine, reduced eGFR, protein or blood in the urine, swelling, high blood pressure, recurrent stones, or other signs of kidney disease.
Can painkillers be taken for kidney-area pain?
Some pain medicines can affect kidney function. People with kidney disease or suspected kidney problems should consult a healthcare professional before taking painkillers regularly.
Conclusion
Pain in both kidney areas can have several causes, and bilateral pain does not automatically mean that both kidneys are diseased. Kidney stones, infections, hydronephrosis, urinary obstruction, and cystic kidney disorders can produce flank discomfort, while muscle strain, spinal conditions, and nerve irritation are also common possibilities.
Pain accompanied by fever, chills, blood in the urine, severe vomiting, difficulty passing urine, or very low urine output requires prompt medical attention.
