Kidney stones

Snake.Had stones since the late 70's mainly from drinking the water about 70km east of you.Since then have moved to U.S. and had to get stones pulverised 2 different times that left a bruise on my stomach and back the size of a hardball.Was told last time I had 1 lg. one and two many small ones to bother counting.Damn pain made me drop to my knees on more than one occasion.Had gall bladder stones also,much,much,much more intense pain than kidney stones.I now drink over 100 oz. of water each day along with Cranberry juice a few times a week.GL.
