Your post was excellent. I didn't mean to imply that merely by learning better techniques would I solve my problems; in fact, much of the "Healthy Guitarist" is devoted to exercises and stretches for guitar players, much like Egoscue's work.
I've exercised at the gym 3-4 times per week all my life, so I realize the importance of fitness, but I will try to harvest past posts on this site to learn some new routines because I know I don't vary them enough.
The fact is, you have certainly created the most optimal opportunity to minimize the negative effects of your activity and that's what we all need to do; since the behaviors mimick so many other life experiences. I love that you get the Egosque material. He is a complicated man with enormous talent for understanding the human condition. If you ever have a chance, go to his studio in California. I have never had the luxury but know people who have worked with him personally. He is fascinating and knowledgeable and quite the character, from what I hear. Keep up the good work! Much of the work people transfer to 'professionals' can truly be discerned within oneself if you 'trust your own being'. That's a Vickism.
