Hello. Fell from top of the stairs. My first hit was on the lower back right rib. Did not notice pain until an hour or so later. Hurt to sleep for several days. Breathing was fine. Could feel moderate pain with a deep inhalation as well as when sneezing. Noticed a cracking or popping feeling on the rib when I pushed on it lightly at a certain angle. I know don't do that! Does that mean it is broken or is this just the cartilage? It has been 17 days since my fall and I feel some improvement. Still hurts when I sneeze the most. Can I still lift weights with this injury? Stretch? Hit golf balls? I am an athlete and know my limits but I don't want to exacerbate the injury. Total rest not an option! Thank you so much for your professional input.
