Thanks for the idea... I have actually seen several chiros (at least 5 or 6). I never saw and benefit from them, unfortunately, and one guy actually made me feel worse. He was an upper cervical chiro, and after seeing him my sleep got all messed up again.
I have seen a post about a guy who sounded similar to me and he got a ton of relief from a chiro who was very good at working the SCM muscles... I suspect it could help me. But it's hard to just bounce from one chiro to another hoping that they have just the right expertise. Not sure how to find the right one.
