Hi,

Last night I was exercising and everything was just fine but I made a wrong move and my shoulder crackled. I move my arm in all the directions and I'm sure it's not dislocated or something but I feel a little pain after it crackled and I feel that something is wrong. Can anyone tell me what is about?
Thanks for help,
Michael

I have "Snapping Scapula" in my left shoulder. It's like a grinding, grating sort of feeling. From what I understand it happens because the soft tissue around your shoulder blade is irritated or something, it can also happen when the bones rub against your rib cage.

Hope that helps :)
