Every time i am sitting upright and breathe deeply or stetch or move my back, i feel a pain just below my right shoulder bone and it clicks. a bit like how people click their knee joints when they bend down. But this click is really loud, and kind of heavy (if that makes sense) and afterwards the shoulder bone aches.
Anyone know what this is? My friend says i should go have an x-ray, but i dont know if its nessecery.
