Rib Cage Injury

While running my dog four nights ago, I tripped and fell.
When I smacked into the cement (with 165 lbs of running momentum), I landed with my left hand fisted between the cement and my chest. I don’t think anything’s broken, my breathing isn’t impacted, and there’s no visible swelling or bruising. It’s just that the pain is INCREASING instead of DECREASING. Is this to be expected? Other that Ibuprofen, any treatment suggestions? Bind it or not? Thanks, Donna
