Pain - The Science of Suffering by Patrick Wall. Despite its forbidding title, this is a very clear and up to date book explaining pain for the non-specialist. If you want to understand how chronic pain occurs and why different treatments are used, I recommend it. Patrick Wall wrote this book in his seventies while suffering the pain of prostate cancer. He was one of the principal scientists researching pain, and founded the journal Pain. He died in August 2001. Published by Weidenfeld and Nicholson, London, 1999. ISBN number 0 297 84255 2.
Healing Back Pain by John E. Sarno. Professor Sarno suggests that a lot of chronic back pain is caused not by structural abnormalities but by Tension Myositis Syndrome - the result of the mind's effort to repress emotions. The pain is real, but can best be treated by psychological methods. Before trying this method, I suggest that you read the What is coccydynia? section and visit your doctor to have the source of your pain investigated. In most cases of coccydynia, there is a physical cause, such as a dislocating coccyx.
