Recovery depends on your health and age and the extent of the damage. Each one is a little different. I don't think exercise makes it better. You've damaged some cartilaginous areas which typically don't grow back, so concentrate on alleviating the inflammation and take it easy on the shoulder for 4-8 weeks.

Depending on your activities, it will be easier to dislocate in the future. It will also be easier and less painful to reset. It will also help you predict changes in the weather.
