Tailbone surgery helps to correct persistent pain in the tailbone area, this is often the last resort after trying non surgical treatments and activities or modifications that have not successfully alleviated the pain.
I don't think so. Yes, they can, how do i know this, i was born with an extended tail bone.. very painful at times, and now that i have lost weight, more than ever! When I was 13 I had a back infection that ate away 1/4 of the bone just above my tailbone. When it grew back it fused with the tailbone, producing an extended tailbone (and apparently reduced flexibility). The doctors said this doesn't happen naturally, and the only people who would have an extended tailbone like this are people who experienced what I did or have had surgery. But perhaps they were talking about that particular TYPE of E.T. because I have one less vertebrae now.
the tailbone wont always be numb sometimes it will be very painful to walk sit or even stand!
