Kidney stones are a common and often excruciatingly painful condition. If you suspect you might have a kidney stone, understanding where the pain is located and what it feels like is crucial for seeking timely medical attention. This article will explain where kidney stone pain is typically felt, what other symptoms to watch for, and when it’s important to see a doctor.
Understanding Kidney Stone Pain Location
Kidney stones form in the kidneys, which are located in your back, just below the rib cage. You have one kidney on each side of your spine. Initially, while a stone is still in the kidney, you might not feel any pain at all. Pain typically begins when the kidney stone starts to move out of the kidney and into the ureter.
Ureters are thin tubes that carry urine from the kidneys to the bladder. When a kidney stone enters the ureter, it can cause a blockage. This blockage leads to a buildup of urine in the kidney and spasms in the ureter as it tries to push the stone through. This process is what causes the characteristic pain of kidney stones.
The location of kidney stone pain can vary depending on where the stone is located in the urinary tract:
- Flank Pain: This is the most common location for kidney stone pain. Flank pain is felt in your side, between your ribs and hip. It can be on either side of your back, depending on which kidney is affected.
- Back Pain: Pain can also radiate to the back, often described as pain below the ribs.
- Lower Abdomen and Groin Pain: As the kidney stone moves down the ureter, the pain often shifts downwards. You may start feeling pain in your lower abdomen and groin area. For men, the pain can radiate to the testicles.
- Pain While Urinating: Once the stone reaches closer to the bladder or urethra, you might experience pain or a burning sensation during urination.
It’s important to remember that the pain can shift location as the stone moves through your urinary tract. You might start with flank pain that then radiates to your groin as the stone progresses.

Characteristics of Kidney Stone Pain
Kidney stone pain is often described as:
- Severe and Sharp: It’s not a dull ache. Kidney stone pain is typically intense and can be excruciating. Some women who have experienced both childbirth and kidney stones report that kidney stone pain can be comparable to labor pain.
- Colicky or Wave-like: The pain tends to come in waves, meaning it intensifies for a period, then subsides, and then comes back again. This is due to the spasms of the ureter as it tries to move the stone.
- Fluctuating Intensity: The intensity of the pain can change and vary.
- Radiating Pain: As mentioned, the pain often radiates or moves from the flank to the lower abdomen and groin.

Accompanying Symptoms of Kidney Stones
Besides the characteristic pain, kidney stones can cause other symptoms, including:
- Changes in Urine:
- Pink, red, or brown urine: This indicates blood in the urine, also known as hematuria, which is a common sign of kidney stones.
- Cloudy or foul-smelling urine: This could suggest a urinary tract infection (UTI) which can sometimes be associated with kidney stones.
- Persistent urge to urinate: You may feel a constant need to pee, even right after emptying your bladder.
- Urinating more frequently than usual: You might find yourself going to the bathroom much more often.
- Urinating in small amounts: Despite the urge to urinate, you might only pass small amounts of urine.
- Nausea and Vomiting: The severe pain can trigger nausea and vomiting.
- Fever and Chills: These symptoms, along with pain, can indicate a kidney infection or UTI, which requires prompt medical attention.

When to Seek Immediate Medical Attention
It’s crucial to know when kidney stone symptoms warrant immediate medical help. Seek emergency medical care if you experience:
- Pain so severe that you cannot get comfortable: If the pain is unbearable and prevents you from sitting still or finding any position of relief.
- Pain accompanied by nausea and vomiting: This combination can indicate a more serious issue.
- Pain with fever and chills: This suggests a possible infection that needs immediate treatment.
- Blood in your urine: While not always an emergency on its own, significant blood in the urine accompanying pain should be evaluated urgently.
- Difficulty passing urine: Inability to urinate is a serious sign of blockage and requires immediate medical intervention.
What Causes Kidney Stones?
Kidney stones form when your urine has too many crystal-forming substances, such as calcium, oxalate, and uric acid. When these substances are more concentrated than the fluid in your urine can dilute, they can crystallize and stick together, forming stones. Lack of substances that prevent crystal sticking can also contribute to stone formation.
Risk Factors for Kidney Stones
Several factors can increase your risk of developing kidney stones:
- Family history: Having a family history of kidney stones increases your likelihood of developing them.
- Dehydration: Not drinking enough fluids is a major risk factor.
- Diet: Diets high in protein, sodium, and sugar can increase risk. High sodium intake is particularly linked to kidney stones.
- Obesity: High BMI and weight gain are associated with increased risk.
- Digestive issues and surgery: Conditions like inflammatory bowel disease and gastric bypass can alter calcium and water absorption, increasing stone risk.
- Medical conditions: Renal tubular acidosis, cystinuria, hyperparathyroidism, and recurrent UTIs are risk factors.
- Certain medications and supplements: Vitamin C, excessive laxative use, calcium-based antacids, and some migraine/depression medications can increase risk.
In Conclusion
Understanding where kidney stone pain occurs and recognizing the associated symptoms are vital for seeking prompt medical attention. Kidney stone pain is typically felt in the flank, back, lower abdomen, and groin, and is characterized by severe, wave-like pain. If you experience these symptoms, especially with accompanying issues like fever, vomiting, or blood in urine, seek medical help immediately. Early diagnosis and treatment can help manage the pain and prevent potential complications.
