Thank you, everyone, for your replies. I've had all the "usual" PT which helped until the strengthening exercises got too strong. Of course, I did not know this at the time, and went for the "no pain, no gain" course of things.

It was actually my last PT who suggested TOS, as everything that was done made things so much worse. I've read up to page 15 of this forum, and I'm really confused about how to find people who know what they are doing. Then there's the problem of finding the time to fit all this in.

This time of year, I work 10-15 hours a day, every day, and have small windows of free time. It's a horrible circle of damage - I need to work to make money, but working makes the pain and numbness worse and also leaves me no time to either investigate and obtain treatment, or to rest from the injuries. I don't even know where to begin to find out about cranio-sacral or myo-fascial stuf!

And yes, music is not only my work but my therapy, as well as WHO I am.
