I have been using this method for years and have had success both for my chronic back pain as well as for relieving asthma attacks. I have had back problems since I was a child and although chiropractic did (and does) wonders for me, Bonnie Prudden's techniques have eased more of the pain than I could have ever hoped for. Using these proven techniques gets the muscles out of spasm so that my chiropractor can get my spine adjusted - and in turn get rid of the associated leg cramps, etc. So much of Ms. Prudden's technique can be done on yourself with the correct tools. All it takes is the patience to study the trigger points and practice the techniques.Bonnie Prudden saved my sanity when I couldn't even walk because of the pain! I would highly recommend the book to anyone who isn't getting relief through other methods. I have even ordered the book for my chiropractor!
