So a week ago me and a few buddies were wrestling around when I took a knee to my right hand side of my chest. I had no real pain for 2 days but around the 3rd day I started to have a slight ache when breathing and slight ache when putting heavy weight on that arm. I assumed I was just recovering from a bruise and didn't do any thing to make it better or worse just rested.As the the days went on it started to hurt worse to where I am on day 6 having some heavier pain can someone explain whats going on and if I need to go to the doctor about this thanks.
