Ok, so its 3 days later and my ribs are still very sore. It hurts to breath deeply, sneezing is excruciating and I have to lie on my right hand side.
Having broken my ribs twice before (once being dump tackled in a game of rugby and once when an over zealous large friend of mine dealt me a serious body blow during some boxing sparring), I'm pretty sure I know what cracked/broken ribs feel like as opposed to the bruised variety.
I also know (having been to hospital twice before with broken ribs) that if you go to hospital with broken ribs they ask if you can breath properly and check for punctures. If there are none they say there is nothing they can do to help. Rather than waste an evening battling drunks and health tourists for attention in my local hospital, I may as well just suck it up.
But it hurts.
