"my first kidney stone.  very painful.  went to er since i didn&#039;t know what was happening.  cat scan = kidney stone ~2mm.  i wasn&#039;t going to die and it would pass.

they 1st gave me iv morphine.  that took the pain down about 20% to a manageable but still very painful level for about 10 minutes then it jumped back up as if i&#039;d had nothing.

they then gave me dilaudid saying it worked on different receptors.  in 2 minutes the pain dropped about 75% and stayed down for about 4 hours until it wore off.

dilaudid seems to work differently than morphine. a great and powerful medication."
