Pain
"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."
