I slipped down the stairs (wooden no stair carpet), and banged down the last 3 or 4 on my coccyx. Had the same dx as everyone else at docs, and basically it took a year for me to be able to sit properly. I was working in a call centre 2 nights a week at the time and had to stand up for my whole 9 hour shift!!!! However, must admit that it very rarely bothers me now 7 years later, unless, like sidge, I'm sitting on a hard surface for a long period of time. my sympathies.
