Done that bin there about 10 yrs. ago. Mine was so bad and I was in so much pain for 12 hrs. that they used the Lithotriptor on the stone to pulverize it. The device uses a very focused sound-shock wave to pulverize the SOB and then you just pass it normally. The pain is like someone sticking a red hot knife in your side and then it moves around your back to the other side and Demerol only the takes the edge off it.
Good luck RPM
