I Fell And Landed On A Coffee Table (low Table)

I fell and landed on a coffee table (low table) and landed on my rib cage. I hit really hard and have pain on the right upper middle of rib cage. It hurts to breath, move, getting in and out of bed really hard to do bending over to pick up something hurts. Can't cough and riding in a car going over bumps really hurts. The fall happened Thurs. and the pain is not getting better. Had an x-ray Friday showed no fractures of the ribs (really surprised me). Could I have damaged my lung?
