Last Saturday, Oct. 22nd I fell on a deck and landed on my ribs on the stairs. I went to Urgent Care and they had me get an xray and it said there are no breaks. But I am in excruciating pain. It hurts to breathe, sit up, lay down, bend, twist, cough, sneeze... you get the idea. I keep feeling a pop in my ribs and it has gotten progressively worse. What could it be? should I go back to the dr?
