For me it was a blockage, which nobody managed to unblock.
Doing pull-ups, the strong latissimus dorsi does most of the work. It probably wont hurt (as much). Doing all the other exercise you've mentioned, stresses the lower and middle trapezius, the rhomboids major and minor, the infraspinatus as well as the serratus anterior, and if any of these muscles develop trigger points, muscles lying underneath their area of referred pain, will probably also develop triggerpoints, which includes the supraspinatus, levator scapulae, teres minor and major, upper trapezius, most of the erector spinae muscles, multifidi and rotatores and so forth and mayhap also the posterior serratus inferior and superior (but that rarely happens). I see from the picture that your latissimus dorsi is highly visible, indicating it is very active. I think your latissimus dorsi does a lot of the work that the muscles attached to your scapulae are supposed to do.
I'd work on activating these muscles. In a couple of months time, see the naprapat, and have him assess your thoracic spine anew. He maight be able to unlock it then.
