Hurt my Tailbone sledding?

I was sledding yesterday, and went off a jump and when we landed (Three girls) I landed right on my tail bone it hurt really bad, and I started dry heaving, and my body was jerking. But all that too say, I can't do anything, theres no bruise... But I can't sit, lay, but I can walk.. I hurt it yesterday at about 6pm.. And its noon now, so its had time... Should I go to the doctor?
