Update: Saw a specialist today. Had xrays ect. She did a bunch of range of motion shit, ect. She says its not a tear. But she said I REALLY aggravated it. Every range of motion test felt fine. With the exception of holding my arm straight out to the side and having her push down while I resist. That was pretty sore. (on that back side of the side delt)
Every since that it has been sore all day again. She said I can return to the gym when I feel ready. I explained to her I plan to go volume and very light with no overhead for a while longer. But ofcourse if theres any pain I will stop. She said to expect some extra soreness in that shoulder while its healing. Also that its a MUST that I go back to doing rotator strength exercises with bands.
I also have bone spurs at the end of each collar bone pointing down. Nothing large but still there.
I know you don't want to hear this, but I would take some time off my friend.
