Hi, I Fell Down 5 Stairs (I Am Moving). I

Hi,
I fell down 5 stairs (I am moving). I really hurt my right side, shoulder and my ribs.
This was 3 days ago, I have obvious bruises on my shoulder but nothing on my ribs. My ribs right under my right breast have been becoming more and more painful every day. It hurts to breathe, cough, laugh and when I bring my arm up.
I have a high pain tolerance and am wondering if I need X-rays.
Please advise.
