Is It Normal To Have Swelling And Puffiness In Shoulder Blade With Rotator Cuff Fracture?

in a labrum tear, and a rotator cuff fracture, in this case, there is a muscle that runs over top of the shoulder, and down the back near the shoulder blade, and there is swelling and puffiness by the shoulder blade. I m wondering what muscle that is and why it is swollen in that area. I know its from the impact of the fall on the shoulder that has caused a domino affect. Just trying to learn a little about this
