pain
"After a fall and suffering a slow decline into osteoarthritis of the right hip, I had been managing pain with Vicodin for the last two years before I went for total joint replacement. Maybe I had built up a tolerance because after surgery, my pain was mind-boggling until it vanished "just like that". I asked the nurse what she just gave me and she said she tried a little Demerol via I.V. Amazing stuff when morphine didn't do it for me!!"
