It really doesn't hurt when lifting. I feel a little twinge of pain when doing upright dumbell pushes, but nothing to slow me down. I have backed off the weight just in case on my shoulder exercises, but no real pain. Making a throwing motion with my left hand also does not hurt.
The pain occurs when I am holding my arm outstretched with some weight (my bow) in my hand, and attempt to draw back.
Something in the very top of my shoulder is damaged, hopefully a supporting tendon or ligament that will heal itself.
Thanks for the replies and making me feel welcome, guys!
