Have you successfully treated Thoracic Outlet Syndrome?

I'm currently experiencing issues now from what I believe to be Thoracic Outlet Syndrome, ranging from facial, shoulder and arm numbness, to radial nerve issues in my forearm and hand, as well as bilateral ulnar nerve pain in my arms and hands.

I've gone to physical therapy, adjusted my posture, bought an ergonomic workstation, and had every diagnostic test imaginable, but the issues still remain. Have any of you had any luck treating TOS? Thanks!
