hypermobile coccyx ... does it hurt when you sit too long :-(

[Guest guest]

Hi all,

I found this interesting site that talks about tailbone pain.

www.coccyx.org   >>  what is coccydynia?

Unstable coccyx

The commonest cause of coccydynia is an unstable coccyx - one which moves

more than normal when you sit down. It may either bend upwards more than normal,

or the joint may partly dislocate, slipping backwards. The pictures below show

unstable coccyxes.

This picture is based on x-rays of the coccyx of someone standing (on the

left) and sitting (on the right). It shows a coccyx which bends up more than

normal on sitting (a hypermobile coccyx). The coccyx is the two lower segments

on the picture, above them is the sacrum. The patient is facing to the left.

The last segment of the coccyx bends upwards much more than it should when the

person sits.
