I haven't done the surgery, but I've had some of those symptoms lately from two sources:

-- Got sloppy about my posture again. Forward head position can pull on parts of your upper back.

-- I did a funny pec minor stretch, but all it did was mess with my shoulder blade.

I can't say what your symptoms are caused by, but maybe that's food for thought.

I got fixed up with PT+OMT today though, so feeling better.

Time for a relaxing nap...
