My advice to you would be is to get your Atlas bone checked by a relevant Chiropractor, who specialises in the cervical spine (neck) if this bone is out just a fraction it can have allsorts of knock on effects to your whole system.
A Chiropractor is trained to notice any slight misalignment i this area and can correct it.
I see the body as a complex piece of engineering, where as if one componant is out a fraction of a mm, the mechanics of the system will fail, gradually over time resulting in a breakdown of fluidity.
I describe it like that as tends to make sense to me much simpler, not that i'm simple but I cant be doing with all the long words ans stuff.
google Dr Windman Atlas, I found it her discription etc easy to understand.
I do my own research, and find my own answers Its good to talk
