Usually the first sign of a kidney stone is intense pain in your mid-back or side. This happens when the stone irritates or blocks a section of your urinary tract. The pain may spread to your groin area and inner side of your thigh (depending on the location of the stone), and the sudden onset of pain may cause nausea and vomiting. The pain may come and go in waves. Patients who are passing kidney stones often find it very difficult to find a comfortable position. There may also be some blood in your urine if the stone has irritated the surrounding tissue.
