I came across my first Pete Egoscue book in a second-hand shop in Skipton. It literally changed my life! We were on holiday and I was in a lot of pain from my back from a combination of sitting around too much and trying to do some walking (I have ankle problems so walking is difficult). My back got so bad that painkillers weren't touching it and I was crying with the pain.
But the Pete Egoscue book helped where nothing else had. I did some simple exercises (nothing too exerting!) and they eased my back enough to do others that would build up the muscles and stop it getting so bad again.
Once I was home and back on my laptop, though, I started getting what I thought were migraines again. I had been free of them on holiday. I ordered this book because it has been specifically written for today's postural pain problems. My 'migraines' turned out to be coming from my neck, which I was holding at odd angles thanks to my computer use.
Egoscue gives sets of simple, easy to remember, exercises for different types of computer users - moderate, average and 'power pc' users. He talks about how to break patterns of pain. I was certainly guilty of that. I used to hold the telephone between my ear and my shoulder so I could input data as I talked. That's a very obvious, stupid thing to do but it is actually something many of us do all the time without realising.
Another big thing that has helped me, apart from this book, is getting laptop stand. It raises the screen so I'm not giving myself neck pain from looking down at it.
I have this and other Pete Egoscue books in the library at the training centre I run. I think they are vital reading for those who want to stay healthy in today's technology-driven environment.
