If the stone is on the right, you should feel the pain from the back, down the right flank into the groin area. The same would be true for the left
kidney. I have had
stones on
both sides. The pain usually only occurs when the stone is passing. If you notice even a hint of blood in your urine, go see your doctor, or, if you have one, your urologist. If the stone has not left the kidney, it can be treated with lithotripsy. Otherwise, you might have to have a more invasive treatment.
