By the way, Kidney stones are nothing to joke about. I had to have surgery to remove mine, which resulted in a second surgery to undo the damage from the first surgery. I had several follow up trips to the emergency room to be cathetered for the internal rip in my penis and then self cathetered myself for a year following surgery to prevent scar tissue from blocking my penis shut. Total nightmare scenario.
Another kidney stone veteran here.
First at age 20, presumed excess calcium because I was drinking alot of milk in college.
Second set, age 54. Presumed cause was vitamin pills or the binders of them. Also could have been protein related during the Adkins diet craze. Fortunately they did not cause blockage and had descended.
Third set age 59. I almost requested an emergency landing on a DEN-JFK flight. Almost certain the cause was from excess tea drinking as that was the only change in diet. Lithotripsy turned these to sand at the Denver kidney stone center and they passed freely.
