When using narcotic pain killers prescribed by a doctor, such as Morphine or Oxycodone. One unpleaseant side effect (Some people enjoy it too) is "The Itchy-Scratchys". This is when you feel itchy all over your body and face and
sometimes it feels "So Good" or "Heavenly" to scratch the skin where it itches that you can
break the skin and still want to
scratch it because it itches so bad.
