Kidney pain is often felt in the side or back, just beneath the lower ribs, rather than directly in the middle of the lower back. Depending on the cause, it may feel like a persistent ache, pressure or sudden, intense pain. It may also spread toward the abdomen or groin. citeturn372046search8
Men searching for kidney pain symptoms may be trying to understand whether discomfort is coming from the kidneys, muscles, bladder, prostate or another part of the urinary system.
The location and pattern of pain can provide useful clues, but they cannot confirm the cause on their own.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides evaluation and management for kidney conditions and related kidney-function concerns.
Where Is Kidney Pain Located in Men?
The kidneys sit toward the back of the upper abdomen, one on each side of the spine. Kidney-related pain is commonly felt in the flank, the area between the lower ribs and the hip.
Depending on the underlying problem, pain may occur in different locations.
Pain on the Right Side
Pain beneath the right ribs or along the right flank can occur with a right kidney stone, kidney infection, obstruction or other kidney conditions. However, gallbladder, digestive and muscular problems can cause pain in a similar area.
Pain on the Left Side
Left-sided flank pain may be associated with a kidney stone, infection, obstruction or other kidney disorder. Spinal and muscular conditions are also common explanations.
Pain That Moves Toward the Groin
A stone moving through the ureter may cause pain that travels from the side or back toward the lower abdomen and groin. In men, this pain may sometimes be felt in a testicle. citeturn372046search1
Sudden testicular pain should not automatically be attributed to a kidney stone. Testicular torsion and other urgent conditions can also cause it and require immediate medical assessment.
Common Kidney Pain Symptoms in Men
The symptoms depend on whether the underlying problem is a stone, infection, obstruction or another condition.
Possible signs include:
-
Dull or sharp pain on one side of the back
-
Sudden, severe pain that comes in waves
-
Pain spreading toward the abdomen or groin
-
Blood in the urine
-
Burning or discomfort during urination
-
Frequent or urgent urination
-
Cloudy or unusually foul-smelling urine
-
Nausea or vomiting
-
Fever or chills
-
Reduced urine output in some cases
Kidney stones can cause sharp pain in the back, side, lower abdomen or groin, along with blood in urine, urinary symptoms and nausea. citeturn372046search0
Not every person experiences all these symptoms. Some kidney conditions cause little or no pain.
Kidney Stone Pain Versus Kidney Infection Pain
Two important causes of kidney-area pain are kidney stones and kidney infection. They can produce overlapping symptoms, but some patterns may help guide evaluation.
| Feature | Kidney stones | Kidney infection |
|---|---|---|
| Pain pattern | Often severe and comes in waves | May cause persistent side or back pain |
| Pain location | Flank, abdomen or groin | Back, side or groin |
| Blood in urine | Can occur | Can occur |
| Burning or frequent urination | Possible | Common in many cases |
| Fever and chills | Concerning for associated infection | Important warning signs |
| Nausea or vomiting | May accompany severe pain | May occur with infection |
A kidney infection can cause fever, chills, painful or frequent urination, back or side pain, and nausea or vomiting. Prompt medical assessment is important because an untreated infection can become serious. citeturn372046search3turn372046search7
Important: A urinary obstruction caused by a stone together with infection may be an emergency. It may require urgent drainage as well as infection treatment.
Other Causes of Kidney-Area Pain in Men
Pain around the kidney region does not always originate in the kidneys.
Muscle Strain
Lifting heavy objects, exercising or making an awkward movement can strain the muscles of the back. Pain may worsen with certain movements or when the affected area is pressed.
Prostate Enlargement or Urinary Retention
An enlarged prostate can interfere with urine flow. Men may experience a weak stream, difficulty starting urination, frequent urination or a feeling that the bladder has not emptied completely. Severe urinary retention needs urgent assessment and can affect kidney function.
Hydronephrosis
Hydronephrosis is swelling of the kidney caused by urine not draining normally. Stones, narrowing of the urinary tract and prostate-related obstruction are among its possible causes.
Kidney Cysts or Other Kidney Conditions
Some kidney cysts, injuries and other kidney disorders can cause flank pain. The likelihood depends on the condition and its severity. citeturn372046search8
Spinal or Nerve Problems
Problems involving the spine, discs or nerves can cause back pain that may be mistaken for kidney pain.
Because these conditions can feel similar, medical assessment is more reliable than trying to diagnose the cause from pain location alone.
Can Kidney Problems Cause Pain Without Urinary Symptoms?
Yes. Some kidney conditions can cause pain without obvious changes in urination. Conversely, some people with kidney disease have no pain at all.
Chronic kidney disease often develops without noticeable symptoms in its early stages. It is usually identified through blood and urine tests, particularly in people with diabetes, high blood pressure or other risk factors. citeturn372046search6
Therefore, the absence of urinary symptoms does not rule out kidney disease, and flank pain alone does not establish that the kidneys are affected.
How Is Kidney Pain Diagnosed?
The appropriate evaluation depends on the pain pattern, symptoms, medical history and examination.
Medical History and Examination
The clinician may ask when the pain started, whether it is constant or intermittent, whether it spreads to the groin, and whether fever, vomiting or urinary symptoms are present.
Urine Tests
Urinalysis can help identify blood, signs of inflammation or other abnormalities. A urine culture may be needed when infection is suspected.
Blood Tests
Depending on the clinical situation, testing may include:
-
Serum creatinine and eGFR
-
Electrolytes
-
Complete blood count
-
Other tests guided by the suspected diagnosis
These tests help assess kidney function and look for signs of infection or complications.
Ultrasound or CT Scan
Ultrasound may help identify hydronephrosis and some kidney stones. A CT scan may be recommended when detailed assessment of a suspected stone or another abdominal condition is needed. citeturn372046search2
Not every patient requires every test. The investigation plan should be individualized.
What Is the Treatment for Kidney Pain in Men?
Treatment depends on the cause rather than the location of the pain.
For kidney stones: Small stones may pass naturally in selected cases, while larger stones, persistent obstruction or ongoing pain may require a procedure such as ureteroscopy with laser lithotripsy, shock wave lithotripsy or percutaneous nephrolithotomy.
For kidney infection: Antibiotics are generally needed when a bacterial kidney infection is diagnosed. The medicine and route of treatment depend on the severity of infection, test results, kidney function and other patient factors.
For urinary obstruction: Treatment focuses on restoring urine flow. Depending on the cause, this may involve a catheter, ureteral stent, nephrostomy or a procedure to treat the obstruction.
For muscular pain: Treatment may involve activity modification, physiotherapy or other appropriate measures after a kidney or other serious cause has been considered.
Pain medicines should be chosen carefully. Certain anti-inflammatory medicines can worsen kidney function in people with chronic kidney disease, dehydration or other risk factors. Do not self-medicate repeatedly for unexplained flank pain.
When Should Men Seek Urgent Medical Care?
Seek urgent medical attention if kidney-area pain is accompanied by:
-
Fever or shaking chills
-
Severe or rapidly worsening pain
-
Repeated vomiting or inability to keep fluids down
-
Blood in urine with significant pain
-
Very little or no urine
-
Difficulty urinating with a painful, full bladder
-
Confusion, fainting or severe weakness
-
Sudden, severe testicular pain
Severe pain, blood in urine or suspected kidney stones should be assessed promptly. Fever and chills with possible urinary obstruction are particularly concerning. citeturn372046search4turn372046search7
If you cannot pass urine at all, seek emergency care rather than waiting for a routine appointment.
How Can Men Protect Their Kidney Health?
Useful measures depend on individual medical conditions, but may include:
-
Keeping blood pressure within the target recommended by a clinician
-
Managing diabetes appropriately
-
Taking prescribed medicines as directed
-
Avoiding unnecessary use of potentially kidney-harming painkillers
-
Following individualized fluid advice
-
Seeking prompt care for urinary infections
-
Getting recurrent kidney stones assessed
-
Attending recommended kidney-function checks
People with known kidney disease, heart failure or fluid restrictions should not increase water intake without medical advice.

Frequently Asked Questions
What are the first kidney pain symptoms in men?
Possible symptoms include pain beneath the lower ribs on one side of the back, discomfort spreading toward the abdomen or groin, blood in urine or urinary symptoms. Early kidney disease, however, may not cause pain.
Can kidney pain spread to the testicles?
Yes. A ureteral stone can cause pain that travels toward the groin or testicle. Sudden severe testicular pain is an emergency and must not be assumed to be caused by a kidney stone.
How can I tell kidney pain from back muscle pain?
Kidney pain is often felt deeper in the flank beneath the ribs and may occur with fever, urinary symptoms or nausea. Muscle pain may change with movement or pressure. These patterns are not definitive, and examination may be necessary.
Does kidney pain always mean kidney stones?
No. Kidney infection, urinary obstruction, cysts, injury and other conditions can cause kidney-area pain. Muscular and spinal conditions can also cause similar discomfort.
Can kidney disease cause lower back pain without fever?
Some kidney conditions can cause pain without fever, but lower back pain is also commonly caused by muscles or the spine. Testing and clinical assessment help determine the cause.
Which doctor should men consult for kidney pain?
A nephrologist evaluates medical kidney conditions, including kidney-function problems and chronic kidney disease. A urologist evaluates many urinary tract problems requiring procedural or surgical treatment, including some kidney stones and obstructions. The appropriate specialist depends on the suspected cause.
Conclusion
Kidney pain symptoms in men can include one-sided flank discomfort, pain spreading toward the groin or testicle, blood in urine and changes in urination. Fever, chills, nausea or vomiting may indicate infection or another problem that needs prompt attention.
However, pain near the kidneys can also come from muscles, the spine, the prostate or other abdominal organs. A reliable diagnosis may require urine tests, blood tests and imaging based on the clinical findings.
Do not ignore severe pain, fever with urinary symptoms, inability to pass urine or sudden testicular pain. Timely evaluation can help identify the cause and prevent complications.
