I think I've hurt my right shoulder. I don't know what caused it but it is painful. I noticed it today while taking bath. I clean my back by applying soap with my hands somewhat like this:
I when I do whats shown above, with my left hand, my fingers reach my right spine of scapula. But when I try to do the same with my right hand, it hurts in the shoulder joint. This is the only motion (orientation of right hand) in which its hurting. That is the reason why it went unnoticed in the gym. I don't do any such motion in the gym.
What to do? What should I avoid in the gym? How to cure it?
