No surgery
My friend has it and the symptoms you have sounded just like his, he's been working out through it. His problem is the front delt is overdeveloped and pulls the shoulder forward, so he's been doing a lot of rear delt work to try and fix it.
in my case he seemed to think it has to do w the worsening of my posture from sitting at a desk for 10+ hours / day. the "slouch" or moving my scapulas forward and down closes the little passageway where the ball of the rotator cuff sits and when i move my arms up the rubbing is what's causing the pain. hopefully it's that simple and some PT and posture work clears this up.
