Nuss bar displacement?

Has anyone had Nuss Bar displacement? I am currently headed to the ER to be checked out and looked at by my doctor, because my husband’s dog pulled my arm pretty hard, and my right side is extremely swollen. Feels like a giant ball and I cannot put my arm down much. So upset if this happened, I have been so careful!

Pics show my left side to show the different and the left side does not hurt…
