Care to share the nerve gliding exercises? Mine at this point (besides yoga anyway) mostly involve just taking the shoulder through its FULL range of motion with and without light resistance (stretchy bands with a door anchor for pulling motions, rolling a foam ball on the floor for pushing), rather than doing anything repetitive in a single plane the way most "exercises" work. (And I really feel the muscles at the inferior point of the scapula, too - have all along.)

Glad you're still making progress!
