I've had a long history of sore neck, shoulders and a bout of chronic costochondritis (inflammation of rib cartiledge) as well as some pre-sciatica. I read about this in Andrew Weil's book, but have never discussed this with anyone who has actually had the therapy. It does sound too good to be true.
I'm in an area with a slew of these practioners, but always like to check with my cure zone contacts first.
