Noone deserves 5 stars but this one is a gem, and is closer to 5 than a 4 alright. If you wanted to fake being a doctor of pain medicine and had no training, this is definitely the book you would want. This, plus a good atlas of injection techniques for fluoro, and another for US would get you started. Pretty easy to understand, to the point, covers a lot of subjects. Or, if you were in family practice or IM, and wanted to learn enough to talk to the local pain doc, maybe show him or her up a little, this book would be your key.However, it does cover quite a number of topics that are not reimbursable - I guess that is good as I believe in some of them, like discography in certain situations, or pulse RF - but some clarification that the approaches are for practical purposes tough to do in reality would be a help.Didn't agree with some of the statements / ideas. However, I've been doing pain since '90, and on reading the book I find a bunch of knowledge that I was not aware of before. It is only a couple of years or so to the next edition, most likely. However, unless you know all there is to know about pain, I'd buy this book anyway.
