As a fellow Kidney Stone Alumni, I approve of this treatment. I got the unfortunate opportunity to discover I'm mostly immune to Morphine during this event. I learned this while in the fetal position on the floor of a small room off the ER at the local Hospital.
Fun times... This was when I was 26, and now at double that age, I still 'perk up' if i get a cramp in my Kidney. That doesn't happen very often, but I do know exactly where my kidney is, and if I get a pain there I quickly start thinking... Oh no, please no!
