Hello! Welcome to HCM. Yes, this can be stone related pain. When stone comes in ureter, urine outflow is obstructed & smooth muscles in ureter contract excessively to overcome the obstruction, resulting in severe colicky pain. Also, this can be musculoskeletal pain. You havent mentioned about trauma, if any or any urinary complaints or fever. Many such patients come to my clinic, to whom I advise ultrasound abdo-pelvis, X-ray KUB, renal function tests, urine & stool routine. Treatment is done accordingly. Consult your doctor for diuretics, analgesics, smooth muscle relaxants like drotaverine etc. Hope this helps. Wish you speedy recovery. Thanks. Regards.
