I have a problem that is somewhat similar to the OP.
Once in a while, I'll be sitting down, minding my own business, normally with my arms crossed, when my shoulder joint feels as though it's trying to pop out of the socket. Just before it strikes, it feels like my shoulder is completely relaxed and has lost all tension. During the episode, I'll feel mild discomforting pain and my body tenses up as the bone feels like it is trying to force itself from the socket. After about 10 seconds, it will pop back in. Depending on how bad it was, the tendons and muscles around the joint will be sore for a day or two, though it sometimes causes no short term pain at all. Any idea what is causing this? It only really affects my right shoulder, rarely the left.
