Shoulder pain, when I lie on my side and kind of pressure the shoulder it literally falls and moves down with a bone sound, as if the bone just slides down I can feel it. Shoulders feel weak and feel like it's going to fall down eventually, feeling too loose as if my arm is going fall down because the shoulder part seems unable to carry the weight. I have had this for a long time, lying on the side and my body literally going down and falling because of my shoulder unable to hold it and aching afterwards but I thought it would be fine and because my bones and joints are not healthy but recently it is happening too much I cannot even sleep cause it aches so much. Sometimes even when running my shoulders feel loose and aches, recently I had an all body joints aching condition but tested negative for rheumatoid and then doctors thought probably depression, but still unknown and so maybe that made the pain more severe because I mentioned I already had this lying down on side my shoulder and my body falling on it because shoulder was probably weak or already damaged.
