This book is a pleasure to read--uses understandable terms--which makes it easy and even fun to read and gain useful facts. One of the above reviews is critical of the simple, easy-to-understand way the book communicates with the reader. Some authors try to impress you with their "extensive vocabulary" rather than really try to inform the reader. The book reveals the causes of sciatica, the various natural, alternative and medical remedies available--and how to avoid flare-ups. The book is well worth the money. I personally have found welcome relief from my sciatica pain following just one of the tips covered in this easy-to-read book.
