I have this as well....I've been told by numerous docs that I pull my chin in without being aware of it to help the CFS fluid get around the congested intersection in the back of my head. I also wake up like that, too, so there must be a reason!
Hi...reversal of cervical lordosis or loss of cervical lordosis is basically the curve in ur neck is not right or gone....this can be to tight muscles pulling on the neck, or a result of whip lash....it can also be the result of posture, as it is often called soldiers neck bcuz of the way they r told to stand at attention and
pull the chin in, it can over time change the curve as well.
If u were in a fall or a MVA that could explain it, and this can be very painful...I also have this issue...and with PT u can gain some of the curve back...but u have to have a very good PT that knows about chiari too.
I am curious if any of these have to do with the chiari.
