I am 6 months into having a L5 S1 disc herniation. Had it not been for this book and some (believe it or not internet sources) I would probably have had unnecessary invasive back injections and or surgery and I would be in constant fear that the pain I was experiencing was a symptom of an impending health crisis. I am by profession an optometrist and have familiarity with medical terminology and have had enough physiology to grasp what the author is discussing in this book. For someone without any medical back ground at all some of what is in here may be less accusable. However, this is by no means a medical text book. The author systematically explains what we know about the origins of Sciatica, and how the medical community through research and experimentation has discovered the primary mechanisms of Saitic nerve pain as well as the natural history of the condition. With the foundation of knowledge you can better cope knowing why your back and leg hurt and that it most likely won't be forever and that it (in most cases) doesn't indicate impending permanent spinal injury; such that one can go on living and begin the rehabilitation process without fear and thus have an even better chance at a positive out come. This book is worth way more than the cost to own it.
