Re: Fractures in sacrum and coccyx
Welcome to the board. Sorry you are in pain. You are correct in that a fracture of the coccyx can take a long time to heal and the pain can last a very long time.
Because there are so many attachments to the coccyx, it is almost impossible to immobilize it -- thus, no brace or cast. Occasionally, when it is really out of alignment and causing problems, surgery is performed, but I understand this is rare.
So, what to do while it is healing? You can get a doughnut or air cushion for sitting that is cut out--hard chairs can be more comfortable than soft, upholstered ones where the cushions envelope the tailbone area.
I would suggest using ice for pain. Or try a heating pad to see if that feels better -- or alternate.
Some suggest that exercise ultimately makes it heal faster and feel better. However, you need to be really careful so as not to do anything that would "reopen" the fracture line, or that would make it worse.
Sometimes it is very painful if you have to strain for a bowel movement. If that is the case, be sure to eat a high fiber diet and maybe use a stool softener.
Hope some of these tips help.
