Ripped something in my shoulder help!

[Edenviolet]

Putting on my jeans today I ripped something in my shoulder as I pulled them up.
It is near the very tip of my shoulder slightly more to the front and I actually felt as if something had torn off the bone (if that's possible??) the pain is really bad and going down my arm a bit. If I lift my arm or lean on anything it gets worse.
No redness or bruising to be seen but it is hurting.

What have I done and will it heal?

Still really sore but have taken nurofen and tried to rest it by not lifting ds too much etc

dont hold it strangely or not use it. thats how you end up with frozen shoulder.
