... it looks as if it's shifting out of socket on its own and if I move it in a jerking motion upwards it puts it right back in socket. A doctor told me that my shoulder slightly dislocates on its own and that I shouldn't worry about it I also have scoliosis and pain on my left shoulder all the time due to these problems can someone explain to me what's wrong please? also I can't lift my shoulder with this problem above my collarbone into the air unless I force it and it pops and hurts. I get pain in my neck and my shoulder and hold back on my left side seem to move in a way that they're not supposed to which is also where my scoliosis is. what can I do to figure out what is wrong so I'm not so much pain constantly & everyday.
