I have a stone in my left kidney can it hurt before it passes. because the kidney hurts?

Kidney stone.: Kidney stones up to 5mm in size will predictably pass on their own. Just drink plenty of water so you produce a lot of urine, dilate those ureters and allow the stone to pass. It may hurt while it's on its way out, but it'll pass. Bigger stones will likely get stuck and will cause tremendous pain and will have to be removed by lithotripsy or cystoscopy.
