If everything has failed for you, check out the alexander technique: http://en.wikipedia.org/wiki/Alexander_technique All kinds of professionals (musicians, programmers, even actors) love it. Basically it improves your posture and gets rid of all the (unconscious) tension in your body. Main cause for many is that they unconsciously pull their head/neck back, which has effects all over your body. It greatly reduced my RSI. The symptoms basically travelled over time, I had RSI on left, right, both arms, wrist, fore-arm, ellbow, and arm-pits. Downside to Alexander Technique is that you have to see a practitioner for a few sessions. You cannot self-teach you with books (i tried).
