Warning Signs of Kidney Stones

Some kidney stones do not cause symptoms. Others may cause sudden, severe pain when they move into the ureter and cause an obstruction. As the stone moves toward the bladder, you may feel a strong urge to urinate, or you may feel a burning sensation. Fever and chills in addition to these symptoms may indicate a urinary tract infection. Contact your doctor immediately if you experience these symptoms:

• sudden, severe pain in your back or lower side
• fever and chills
• weakness
• nausea and vomiting
• cloudy or foul-smelling urine
• blood in your urine
• a frequent need to urinate in small amounts
• a burning sensation during urination
• an inability to urinate although your bladder feels full
