Anyone ever have a light rotator injury?

Monday at work, spun out on a icy hill, putting chains on, something in my right shoulder let go.
The pain was insane.
The next day saw the Doctor, and was diagnosed with a light rotator injury, and will be off for a minimum of 2 weeks.
Have to get an ultra sound done, then get physiotherapy, after that, anyone have an injury like this?
I can’t lift my arm on it’s own, hanging down I have no pain lift it and I scream, I have full power on an arm curl, and no pain in my arm, all in the shoulder.
Anyone have an injury like this and how long were you down?
And what did you have to do to get back at it again?
