yeah, when i was a kid, probably about 8 or 9, my full-grown dog tried running between my legs when i was standing on a sidewalk. it threw me in the air and i fractured my tailbone.
i couldn't sit right on my ass for about a month, but it was pretty good after that. it might have been because i was pretty young, so it might have healed a bit quicker.
oh, and yeah, stool softener would have helped. i remember shitting hurt pretty bad sometimes.
