I have a constant stabbing pain in my lower back right side by kidney and feels like i have been stated in the stomach bottom right by belly button?

Kidney Stone v other: This is a frequent presentation of kidney stone: severe, sharp pain in kidney region.As stone moves along ureter, pain moves and can become abdominal & pelvic until it passes.Multiple stones= multiple pain regions. Bloody pee can be tell-tale.Other causes-neurologic,musculoskeletal, appendicitis, etc. A good history, labs, & hands-on exam can help determine cause,severity,danger,& proper treatment
