Kidney Stone Symptoms: What You Need to Know

Kidney stones can cause a variety of symptoms depending on their size and location within the urinary tract. One of the most common and painful symptoms is acute renal colic, which typically occurs when a stone blocks the flow of urine in the ureter or renal pelvis. This can lead to severe flank pain and discomfort, often described as one of the most intense types of pain a person can experience.

Sharp, Radiating Pain Is a Key Indicator

Many individuals experience intermittent, cramping pain in the lower back or abdomen that can radiate to the groin or genital area. This radiating pain is often sudden and can be accompanied by a feeling of restlessness, as many patients find it difficult to sit still or get comfortable.

Nausea and Vomiting Often Accompany Severe Pain

Due to the involvement of visceral nerve reflexes, especially when stones cause spasms in the upper ureter, many patients suffer from nausea and vomiting alongside the intense pain. These symptoms can worsen during pain episodes and may not be relieved easily.

Blood in the Urine Can Be a Visible Sign

In some cases, patients may notice visible blood in their urine, known as gross hematuria. This occurs when the stone scrapes the lining of the ureter, causing bleeding. Blood in the urine may appear pink, red, or brownish and is often a clear warning sign that something is wrong.

Fever and Chills Suggest a Possible Infection

If a kidney stone causes a blockage and leads to a urinary tract infection, individuals may experience fever, chills, and general malaise. These symptoms require immediate medical attention, as they can indicate a serious complication.

If you're experiencing any of these symptoms, especially severe flank pain or visible blood in your urine, it's important to seek medical evaluation. Early diagnosis and treatment can help prevent complications and provide relief from discomfort.
