I was operated for removal of kidney stone (22 mm), which passed from kidney (right) to ureter, through laser lithotripsy 5 months back. Though I have recovered, sometimes I feel mild pain in my right abdomen while bending, turning or doing yoga exercises. There are two kidney stones of the size of 4 mm and 6 mm in my left kidney. Presently I am taking ayurvedic medicine Chandraprabha vati and cystone tablets regularly. What better medicine would you suggest for the removal of stones and also to overcome the pain.
