how do i know if i have a kidney stone

Signs that a person may have a kidney stone include severe, sharp pain in the back, side, abdomen, or groin, often described as waves of intense pain that can come and go. Other symptoms include pain or a burning sensation during urination, blood in the urine (which may be red, pink, or brown), cloudy or foul-smelling urine, frequent or urgent need to urinate, nausea, vomiting, fever, and chills if an infection is present. The pain may start suddenly and can vary in location as the stone moves through the urinary tract. Some small kidney stones may not cause any symptoms and can pass unnoticed. It is important to seek medical attention if experiencing these symptoms, especially if there are signs of infection like fever or if there is difficulty urinating.
