Having been diagnosed with referred pain caused by compression in the spine, I was told to carry on taking the prescribed painkillers and do some exercises set by the consultant. These exercises did help with the pain I got in my feet, but did nothing (if not actually made it worse)for the pain in my back, shoulder and hip joints. So I took up Yoga for Healthy Lower Backs, a course offered by one of the Yoga teachers who took part in the trials on which this book is based. After 7 weeks, I'm virtually off the codeine-phosphate tablets (only rarely needed now) and I'm pain-free a lot of the time. And if I am experiencing pain, I can do a posture and find relief - even at work.
The book itself is very clear, with detailed instructions and clear photographs. The postures are explained in more detail in a later section of the book, allowing you to just look at the quick descriptions while you are doing the postures, and reading up in detail later. It gives you a course to follow, so you don't necessarily need to attend a class and allows you to practise at home, in the knowledge that you are doing the right kind of things safely. It is very gentle, taking into account that you might not be able to have the full range of movement / flexibility to do a classical posture, and it offers you lots of alternative ways to do the posture without hurting yourself.
I love the section "What to Do if You Get a Painful Back Episode", as it quickly gives you useful advice and postures that you can do almost on the spot, using office or home furniture to get relief. If you do decide to make Yoga part of your life, it also provides details as to how to go about finding a good teacher / class.
Finally, the book details the research the book is based on, which you can use to persuade sceptical medics.
