I broke my tail bone in 2010 but never was treated for it because I was busy nursing my broken wrist.( They don't do much for it anyway but I probably should have gotten a X-ray)
It took much longer than the wrist to heal and I still have pain. TMI warning - Especially after using the bathroom which makes me wonder how much of an issue this will be when I'm trying to push a baby out.

Its a while before I am the one giving birth (KU my wife first) but this is something that I've wondered about.

Has anyone had a broken tailbone? Did it affect you during or after birth?
