Maybe about 4-5 months ago i hurt my shoulder while playing basketball. I went up for a layup and they pulled my arm down and i felt something weird in my shoulder. I took time off lifting weights because i thought i should rest it, but after 3 weeks pain did not leave. So i did shoulder workout and the pain went away slowly and slowly and i have not had it for a few months until today i hurt it again while wrestliing. It hurts when i flex it and when i move my arm up and down fast.
