Was it a full anterior dislocation? X-rays were good following reduction?
How old are you? In patients under 40, an anterior dislocation following a fall will likely coincide with a torn labrum. In patients over 40, a torn rotator cuff. Given your history of rotator cuff issues, well that complicates things.
You need to see an ortho.
Depending on your age, you are either less or more likely to have recurrent instability and future sublaxations and dislocations. The younger you are, the more likely you are to experience future events. Much of it will depend on the severity of the damage to your soft tissues, and how your rehab goes.
In June of this year, I suffered my seventh anterior dislocation of my right shoulder. I had a labrum repair and debridement in 2001, and have dislocated five times since then. I have surgery scheduled again for September 15th of this year. Rather than rehash all that, I'll just link the thread.

More and more now, the specialists are advising against prolonged use of an immobilizer or sling following a dislocation. Like, a few days at most, and then beginning initial PT to not limit your ROM and lose all your strength. I would think, in a best case scenario, that you're several months away from throwing at least. That is a lot of trauma to that joint. But, I'm just a patient, not an expert, so
PLEASE SEE AN ORTHO.
