Yes. I have a friend who fell down a flight of stairs 3 hours after her wedding. She endured the pain and continued on her Jamaican Honeymoon.

Saw the doc after returning and, indeed, she had broke her tail bone. Doctor gave her a donut to set on..told her to sleep on her tummy to keep the weight off it. We are bringing her one of those kneeling chairs to work on at her desk.
She asked me about possible exercises she could do in her situation. She is very fit and hits the gym every day. But will be taking a couple of weeks off to recoup.. She wants to know what, if any, exercises she can do on returning to the gym that will not cause a problem. Anything she does at this point hurts including picking up a suitcase..etc.
Anyone have experience with a cracked butt? (I've been just waiting to say that)

I got smacked when I mentioned it to her. I deserved it. umm. Bless her heart.
Any advice will be appreciated.
