I have just started (second week) and I notice I get a dull pain and a feeling of a mechanical block medial to my left shoulder, above my clavicle when I do this exercise. I do not get this sensation on the right.
My left should has been a problem for years, and I have spent about a year doing 10 daily dislocates with an unweighted PVC pipe and YTWL's (though really have not made any progress, hence the change in program--still pretty wide on the dislocates)
Aside from the standard "get it checked out", anyone have similar feeling or any thoughts?
