Query: A doctor told him he was a hopeless case.

Pain--My Friend, by Ed Guziejka, is a groundbreaking book, which tells the experience of a 40 year old man with disabling pain in his back and elsewhere. A doctor, in effect, tells him that he is a hopeless case. Another doctor refers him to a Pain Unit, where he embarks on an arduous road to recovery. The staff there consists of experts in the techniques of physical and psychological therapies. The reader gets an insider's view of the way these treatments are carried out, along with Ed's emotional reactions to them. He works hard under the staff's direction, and the results are dramatic.As a physician, specializing in psychiatry, I found this book clear and fascinating. It gives an inside-out view of psychosomatic medicine. It should be read by all health professionals as well as by all who suffer from chronic pain.
