Matt,
3 months ago, I was drunk-driving motorcycles in my backyard a looped the bike. Not my tailbone, but just above, I am sure I broke something. I had a bruise probably 3" by 10" across the area. Had to drive to the boat show in L.A the next AM. Let me tell you how nice of a ride that was! I have pics, really - anyone wanna see? No, didn't think so. I will save you the pain of that! Anyway, it STILL hurts, but not too bad. I am sure the tailbone itself hurts like heck. I am sure I did that in my younger days, but I had a better selection of drugs back then
Get it checked out just to be safe. Not like they can cast it or anything, but best to get checked out anyway! (I did not, so I guess I really don't know what I am talking about).
Steve - That's wrong dude! You are not getting any younger! Your time will come!
