I have been through every kind of back pain treatment except surgery, trying to resolve major injuries in my body. If you were to ask me if I had tried 'this or that' for my back, I bet anything I'd say yes, including mega drugs and cortisone shots. None of it really helped. Some of it made it worse. And I've been doing it for 20 years. Nothing has relieved tension and pain so effortlessly and quickly than Ethan's technique.
