Is it possible to have bone spurs in your tail bone?

Possible anywhere &: usually simply calcification extending into ligaments attached to a bone, sometimes blamed as a "cause" of pain yet mostly because they may be seen on shadowgrams (i.e. X-Rays: images of photons of higher frequency than visible or UV light; conventional names electromagnetic energy & body more transparent). Do "spurs" cause pain, evidence questionable at best. Reason for calcification bigger issue

Yes: bone spurs can happen anywhere in the body. Often they show up on xrays, but aren't the real cause of pain.

Maybe: The term Spurs doesn't apply here. It's possible to have fusion of the tiny bony which comprise the coccyx. Also one can have coccydynia with or without such fusion.
