This is a great book for a select group of people. If you are a person who is new to chronic pain then the Mayo Clinic's guide will likely be very informative and helpful. But if you've been dealing with your pain for a while, this probably won't be too insightful. 

I'm a healthcare provider and I help many people with chronic pain syndromes. There are tips/suggestions in this book that I will incorporate in my treatment plans with these patients.
