Can you pay privately for couple visits and see Art and learn some of the basic mobilizing he teaches with the help of props? He starts mobilizing the very first day and also teaches the self mobilizing the very first day itself.
If you can have 2 or 3 sessions with him and James and purchase the props and work on it everyday and also work with your local PT on your WC would that work for you?
I had to do something similar for scar related issues after my scalenectomy in 2010, since I could only go to him once a month from Northern Cal and have 2 or 3 sessions with them each time I went there.
