When I was in 7th grade I fell down some stairs and broke my tailbone. When I was in 8th grade I was at a creek with my brother jumping off a rope in to the water. I slipped and fell down the cliff and broke my tailbone again. I remember it hurting and I remember not being able to sit normally for a while. But I do not remember how long it took to heal. The only thing that ever "bothered" me afterwards was I could pop it back in to place (just like you pop your knuckles). It never hurt and if I'd ever get uncomfortable I'd just pop it and be fine.
Now I'm 30, on December 4, 2010 I was at my friends daughters birthday party at a skating rink. I was doing really well until this kid swooped out of nowhere and took me down. I fell straight back on my tailbone. It hurt, not horrible pain though. I laughed it off and got back up. A few hours later the pain set in and I figured I just bruised it.
The next morning I could barely move. Remembering my past experience of a broken tailbone - I knew there really wasn't much a doctor could do. So I decided to suffer through the pain. After six and a half months of pain I decided to see what the doctor could do. I went to a chiropractor. He adjusted my hips and popped my tailbone back in place. He did take x-rays. Turns out I did break it when I fell in December but it healed after two weeks. It's still jammed. He gave me an exercise to do and said I have to go back a few more times to have it adjusted again. The first four days after he popped it back hurt more than before he did anything. Now it's not SO bad. Still bothers me to sit for long periods of time. Getting up from the sitting position isn't comfortable.
I went and bought a $3.00 children's floatie/tube to sit on. That seems to help. I have now broken my tailbone three times. Most people don't ever break this bone. Hopefully the third time's the charm and I won't have to go through this anymore. Sigh....
