If he t was a torn rotator cuff you wouldn’t be healing this quickly.! I had one and it took weeks to get pain free.
If I had taken a fall and noted pain almost immediately, then I would have been more worried. This pain didn't start getting bad until a few hours later and then progressively got worse until I felt like an invalid and couldn't do anything. And then it was pretty bad for two days with little improvement. But it seems like its getting better now and I will just be a little more considerate to myself in the future.
