pain
"Had surgery and was given Nubain in IV while at the hospital recovering  when dilaudid wasn't working. It un-did all the previous pain meds within 10-15 min and did nothing in their place! I could feel everything as if I was on the surgery table freshly opened. The pain caused me to go into a slight shock rrom the intensity. I had a to be put on oxygen for a few hours and back on dilaudid. Never ever again."
