There have been a few places who have specifically specialized in "occupational injuries suffered by musicians." These can be very difficult to dig out, but a sparse few public reports have indicated some successes, and at least a place of this kind would recognize the relationships between your injuries and your music.

You may be able to find something with Google, but if your town - or a nearby one - has a symphony orchestra or if a local/nearby university has a fairly large music department, they might reply to a personal request for help directed to a specific person that you can identify. Deans of music departments, Concert Masters (first violins) or Conductors at symphonies, may know who in their music circles has similar problems and has found good/helpful therapy.

Be BOLD (but be polite). Find out who might know something specific to your problem, and ask them directly. The worst they can do is ignore you.
