Symptoms of Kidney Stones

Kidney stones are small, hard deposits of minerals and acid salts. Kidney stones may form when your urine contains more crystal-forming substances than the fluid in your urine can dilute. If the stone becomes lodged in the ureter, it can be difficult and painful to pass. Symptoms of kidney stones may include persistent pain on one side of the back, nausea, vomiting, bloody urine, frequent sensation to urinate, or pain or burning while urinating, and fever and chills, which could indicate an infection. Most of the time, treatment consists of drinking lots of water to help pass the stone, and pain management. Medical procedures may be needed to remove or break up larger stones.
