Shoulder instability?

Weight in some positions, particularly carrying something relaxed in both hands (like you would carry textbooks just above your waist), will half dislocate both shoulders. Even a hard shiver with no weights will turn one or both out. You can see the ball of my shoulder outside of the cup but its not completely dislocated. This is called shoulder instability where the tendons stretch too easily. It isn't painful unless they stay that way for several minutes.

Strong muscles can really help hold the bones together, but if you train them with the wrong balance you can worsen the problem. Stronglifts seems very natural and unlikely to unbalance nature, but I'm not sure. What do you think? Do I need to see a sports doctor?
