Hey Otis,
Its geezerglide, I just noticed this thread, hope everyting is better.
I had Kidney pain on March 27 coming back from Phoenix to Calgary, pain was terrible, had to stop at the Emergency Ward in St. George Utah, advised had Kidney Stone passing, told me it would take from a week to a month to pass, gave me pain killers and sent me on my way.
Pain stopped with medication and then stopped completely without any drug, thought Stone had passed. Boy was I mistaken on May 23 the pain came back with avenges. Admitted to Hospital where next morning they performed an Ureteroscopy (Basket Extraction) woke up and an hour later they sent me home, so since May no more problems.
Otis lets hope its just a Kidney Stone and they will Roto Rooter it out and you will be all better.
Good Luck and take care,
geezerglide
