This is really hard to explain but I want find out whats wrong. When I spread my arms out and my shoulder blades come together I hear a loose sound in neck or upper back(not sure which). There is no pain, but I hear this might be cervical misalignment. I think I am the only one who can hear it though. Its not really a clicking sound but a "Loose" sound. I think I may have got this from mediocre posture or shoulder pressing exercise(maybe both or some unknown reason) I don't know. I am scared though cause I don't know whats going on.
