I think I read that book - the title sounds familiar.
I liked this one better
The Pain Cure
by Dharma Singh Khalsa , MD with Cameron Stauth
The proven Medical Program that helps end your Chronic Pain

What i read so far is about different levels of chronic pain and how it creates it's own cycle in the brain, spasms, referred pain- like headaches, TMJ, sinus problems, ect.

Pg 33- "chronic pain syndrome is characterized by physical inactivity, inadequate sleep, depression, poor nutrition, fear, anxiety, reliance on medications, and mental lethargy...."these traits are almost certain to lock in- and amplify- pain signals that have become engraved upon the nervous system."

She advocates nutritional therapy, physical therapy, medication changes{ to natural,homeopathic and herbs}and mental and spiritual pain control

It may not work for all completely - but maybe some it will help.
