I fell off my bike last year and suffered a bad rotator cuff tear. Fearing dislocation, I immediately rushed to the top orthopedic nassau county and he told me that I had stretched my rotator cuff. He advised me PT in the beginning and if after 3 weeks the injury didn't improve, I would have to go for surgery. But my physiotherapist was a skilled one and after diligently following his therapy routines, I didn't need to go for any surgery. Go for PT. It is the best bet.
