I had RSI, chronic ankle pain after an injury, and back pain. I bought all sorts of ergonomic solutions. Some helped, but none completely. I was getting desperate since, as mentioned, typing is how I pay the bills. I can't just STOP.

I was scouring the net and ran across a developer who swore that The Mindbody Prescription: Healing the Body, Healing the Pain by Sarno fixed his issues. I looked him up, proved to myself he was a dev and then basically said, fuck it, let's try it despite it seeming woo-woo to the extreme.

Little to no pain to this day. This was after MONTHS of PT and ergonomic changes that didn't solve the problem.

Anyway. Just my two cents.
