What Causes Extreme Pain In Ribs?

My ribs are EXTREMELY sore after laying down on the edge of a pier on a lake to reach a cell phone that dropped into the water. I m thinking it s just sore because all my weight was on the edge of the wood. No swelling, just a lot of pain when I sneeze, breath too deeply, touch it. stand up too straight or bend over. This happened Friday afternoon and it got worse today after doing some work outside; raking the grass, taking things out of the garage attic, hooking up the hoses again, etc. Hope you can help. Feels best just laying down on my back with a hot pad on it.
