I have been treating my Mom's neck using core work. When I build a womb around one cervical vertebra, poking it with a stick, chasing it around,I have the image of very fine gas bubbles rushing out the base the vertebra ( the edge connecting the disc). After the bubbles stop releasing and poking is also done. I have the same thing happened with the rest 4 vertebras. I'm not thinking of steam release at that time but could it be the same thing ?

P.S. my experience is that not even I have to womb the cervical vertebra one at a time. Some times, you have to womb both side separtely to gain good result ( embryologically speaking, each vertebra is formed by fusing two developing ossification center at the spinous process)

Don't get confused thinking that the "interesting things" are of particular significance. They are simply that, "interesting things". In my opinion, the bubbles have nothing to do with "steam release".

If you are getting alignment doing all of the cervical vertebra at once great, however it is difficult to get consistency doing it that way and it is much more difficult to be specific for the effect desired.

Thanks, Alain . for such a quick reply.
