Hello, I slipped down stairs a week ago and bruised my back, thought maybe I broke a rib, but no problem breathing. It has been 10 days, pain is going away thanks to Ibuprofen 800, rest and ice. I didnt have much of a bruise, it was a little yellow after 2 days but went away. Am I at any risk for clotting? I have NO signs of blood coming from me.
