One thing I just thought of that I wonder if it means something:
Whenever I get this burning trigger point sensation on the upper corner of my scapula, raising my arm above my head actually alleviates it. So it feels like the scapula is in a better position when I raise the arm above my head than when it hangs down on my side. To get relief I usually raise my elbow to the ceiling and put my hand on my neck. Any conclusion to draw from that? I always though OH position was ‘worse’ for the shoulders.
