Kidney stones can cause a range of symptoms, often depending on their size, location, and whether they obstruct urine flow. Severe pain is the most common symptom, typically starting suddenly and radiating from the lower back to the abdomen or groin. This pain, known as renal colic, may come in waves and fluctuate in intensity.

Other symptoms include blood in the urine (hematuria), which can make the urine appear pink, red, or brown. Cloudy or foul-smelling urine may occur if an infection is present. Individuals may also experience frequent urges to urinate, with only small amounts of urine being passed at a time.

In some cases, kidney stones cause pain or burning sensations during urination, similar to symptoms of a urinary tract infection. Nausea and vomiting are common, especially when the pain is severe or accompanied by an infection.

As kidney stones can obstruct the flow of urine, some people experience difficulty urinating or a sense of incomplete bladder emptying. Fever and chills may develop if there is a concurrent infection, which is a medical emergency.

Timely diagnosis and treatment are crucial to prevent complications, such as kidney damage or recurrent infections. Seek medical attention if you experience any of these symptoms.
