I've also been treating RSI in the framework of Mindbody Prescription. I'm still just starting with meditation, but it seems like the main skill it teaches (this post describes it well: https://news.ycombinator.com/item?id=8670184) is precisely what's good for getting over the RSI(like) problem: the main thing is to understand the 'sensations' aren't something that you need to deal with when they arise, it's okay if they arise—just let them pass. I'd gotten into a way of thinking that if the sensations were there it meant things were going poorly, if not they were going well; while what seems better is, things are okay either way. You don't want to stop the sensations, you want to understand they aren't harmful. I've done a decent survey of meditation literature, and I think a good overview from a number of perspectives would be this one: http://www.amazon.com/Beginners-Guide-Meditation-Inspiration...
Also, I thought this book was better than any of Sarno's for TMS stuff http://www.amazon.com/Rapid-Recovery-Back-Neck-Pain-ebook/dp...
Lemme know if you have other questions or anything.
