Hypnosis for pain relief

So Patterson found a script for inducing hypnosis in a book, and read it out to the patient. It was designed so that when the nurses later touched the man on the shoulder during his wound care, he would go into a trance. “When I went back to see what had happened, the ward was buzzing,” says Patterson. “They said, ‘What did you do to that guy? We touched him on the shoulder and he fell asleep.’ It was astounding.”
