I did a partial dislocation to my shoulder and which has resulted in a rather unstable shoulder. I suggest that you go and see a physio to get an exercise rehab program so that you can build you strength in the shoulder blade region. My rehab program has consisted of working on the shoulder stabiliser muscles such as the Wikipedia reference-linkrotator cuff and also core muscle work.

That is what I have been advised by my shoulder specialists. It's better to act quickly rather than leaving it. I left my first shoulder injury for months and didn't treat it and ended up doing a partial dislocation. The partial dislocation has caused quite a few problems, probably also due to the first injury.
