Pain related symptoms of kidney problems: Our kidneys are vital, fist-sized, bean-shaped organs that sit on either side of the spine, just below the rib cage. Their primary function is to filter waste and excess water from our blood, which is then converted into urine and expelled from the body. These remarkable organs are responsible for maintaining a healthy balance of fluids and electrolytes, regulating blood pressure, and producing hormones that support bone health and the creation of red blood cells. Dr Navinath M MD(Med)(AIIMS), DM(Nephro)(AIIMS), DNB(Nephro), MNAMSConsultant Nephrologist and Renal Transplant Physician, Asian Institute of Nephrology and Urology, Nungambakkam, Chennai talks about their critical role and how it’s essential to understand the signs that something might be amiss, including pain-related symptoms.
Understanding the Silent Threat
Kidney disease is often called a “silent killer” because it can progress without any noticeable symptoms in its early stages. Conditions like diabetes and hypertension (high blood pressure) are the most common culprits behind chronic kidney damage. Unfortunately, early-stage kidney damage may not cause any pain or discomfort, making it difficult to detect without proper medical screening.
This is why regular check-ups are so crucial, especially for those at high risk. If you have a history of diabetes or high blood pressure, getting your kidney function tested through routine blood and urine tests and blood pressure measurements is vital, even if you feel perfectly healthy.

When Kidney Problems Cause Pain
While many kidney conditions are asymptomatic in their early phases, some—like kidney stones, infections, or tumors—can cause significant pain. What’s surprising to many is that this pain isn’t always confined to the area where the kidneys are located, which is the posterior region between the lower ribs and the hips.
Sometimes, the pain from a kidney issue can be a “referred pain,” meaning it’s felt in a different part of the body. A classic example is a ureteric colic, a sharp, intense pain caused by a kidney stone or a blood clot from a tumor blocking the ureter (the tube connecting the kidney to the bladder). This can cause pain that radiates from the back to the groin or even the genitalia.
Common and Uncommon Pain Locations
Understanding where kidney-related pain can show up is the first step toward seeking timely medical help.
1. Lower Back Pain
This is one of the most common signs of a kidney issue. Because the kidneys are situated in the lower back, inflammation or acute swelling of the organ due to a kidney stone, tumor, or a kidney infection (pyelonephritis) can manifest as a persistent ache in this area. It’s often mistaken for a simple muscle strain, but kidney pain is typically deeper and may be accompanied by other symptoms like fever or changes in urination.
2. Groin and Genitalia Pain
Referred pain from the kidneys can travel down to the groin and genitalia. This characteristic “loin to groin” pain is a hallmark of a ureteric colic. The excruciating pain is caused by the ureter’s attempt to dislodge a stone or blockage. It’s an unforgettable sensation that warrants immediate medical attention.

3. Abdominal Pain
While not as common, kidney problems can sometimes cause abdominal pain. A dull, aching sensation in the abdomen can be a sign of a severe kidney infection or the formation of a kidney abscess. This pain is often accompanied by fever and a general feeling of being unwell.
4. Chest Pain
Kidneys don’t directly cause chest pain, but advanced kidney failure can lead to serious complications that do. As waste products build up in the body, they can cause inflammation of the pericardium—the sac surrounding the heart—a condition known as pericarditis. This can result in sharp chest pain, which is a symptom of a very serious, late-stage problem.
5. Leg Pain and Swelling
In patients with diabetes, nerve damage (neuropathy) can cause a burning sensation or numbness in the legs and feet. Many of these individuals are also found to have underlying kidney dysfunction. Therefore, leg pain and swelling in people at risk for kidney damage, such as those with diabetes or hypertension, can serve as an indirect warning sign that their kidneys are struggling.
The Bottom Line
Early-stage kidney disease typically does not cause pain or other noticeable symptoms. When pain does occur, it may not be limited to the kidney’s location. A kidney stone or tumor can cause pain that radiates from the back to the groin, a condition known as ureteric colic.
If you have risk factors for kidney disease, don’t wait for pain to appear. Consult your doctor for regular screening to catch any issues before they become life-threatening. Paying attention to your body and understanding these subtle and not-so-subtle signs can make all the difference in protecting your long-term health.
Dr. Uday Dipakrao Gajare , Consultant – nephrologist from Asian Institute of Nephrology and Urology, Vizag, breaks down the weird places kidney trouble can show up:
1. Back & Sides
You know that dull ache that just lingers around your lower back, right under the ribs? Or those sharp, stabbing pains that come and go like your least favorite relative? Yeah, could be your kidneys sending up a flare—think infections or stones.
2. Belly & Groin
Impacted kidney stones is one the most painful situation one can ever experience, pain that starts in your stomach and shoots down to your groin like a bolt of lightning, and won’t subside unless its addressed. People say it’s as painful as the childbirth
3. Head
Here’s a weird one—your kidneys and your blood pressure are like frenemies. When your kidneys aren’t pulling their weight, your blood pressure shoots up, and suddenly you’re dealing with pounding headaches, dizziness, or vision that goes fuzzy around the edges and blurry.
4. Legs & Ankles
Notice your feet or ankles swelling up? That’s your kidneys slacking on their fluid removal gig. Usually not painful, but it’s uncomfortable like trying to walk with bricks strapped to your feet.
5. Chest
When things get really dicey (think severe kidney failure), you can end up with fluid crowding your lungs or heart. Cue chest tightness and gasping for air typically more on lying down. People sometimes freak out thinking it’s a heart attack, but sometimes it’s your kidneys playing dirty.
Doctor’s Note:
kidney disease doesn’t always announce itself with sirens and flashing lights. Sometimes it’s sneaky as heck. If you’re getting any of these symptoms—especially if your pee looks or smells weird—don’t mess around. Go get checked. A few simple tests (urine, creatinine, ultrasound) can catch most issues before they turn into a nightmare.
Bottom line:
Catch kidney problems early, and you’ve got a fighting chance to slow things down or even turn it around. Better not to ignore the warning signs, else you’ll be rolling the dice with your health. Listen to your body, talk to a doctor, and don’t wait till things get ugly.
