I saw a PT who uses a pain neuroscience education approach and she infuriated me with her condescending, pat, grade-school level explanations of nervous system sensitization. Then I read this book and was convinced that they were pretty much right on. Full of great information about how pain and damage are not the same thing, but pain can't be ignored either. It's a process of gradually reeducating your nervous system about what your body's real limits are, and it can't be rushed.
At the same time I got the impression that authors really don't believe in the risk of re-injury, or in people who have actual ongoing tissue problems that can't be fixed just by addressing pain. This is a grievous oversight because it's hard to imagine someone recovering from a torn ACL or a ruptured spinal disc NOT wanting to know "okay, if pain doesn't automatically mean I'm hurting myself, how DO I know I'm hurting myself?" Also, people whose pain arises from ongoing trauma or from a complex and ongoing disorder like, say, Ehlers-Danlos, will find themselves very badly served -- and horribly condescended to -- by a PNE approach.
Still, I learned a ton from this book and in my personal case, a PNE approach did help me get back to exercise after years of worrying about reinjury and feeling like my back was just permanently "touchy." If you have pain that's preventing you from doing the activities you want to do, you probably don't want to read this book -- you want to read "Why do I hurt" or one of the other briefer, more focused books targeted at laypeople. But if you're the kind of person who's fascinated by what your body is doing, or if you've read the lay-focused books and it sounded like superficial folderol, this is the textbook for you.
