Welcome to the HW Chronic Pain forum, although we're always sorry anyone has to be here. It's a great place for support and information, although we're not doctors.
Are you looking for something about chronic pain? There are a lot of different books there, and your therapist may be able to recommend something. I'm slowly working my way through Reversing Chronic Pain by Maggie Phillips, Ph.D. Many of the strategies and techniques are valid and useful, although I'm always leary of titles that refer to getting rid of pain as opposed to managing it. There are a few good workbooks. too. One thing I've done is search resources (you can search through the Healing Well resource directory) and then maybe go to a local library or bookstore and browse through titles to see what speaks to me.
You may also want to search sites such as the American Pain Foundation, American Chronic Pain Association, American Pain Society and others if you're looking for more scientific links.
I'm sure others here will add their ideas, too.
