If you haven't tried it already, I recommend looking into an upper cervical care modality like NUCCA. I believe atlas subluxation is vastly underdiagnosed because most practitioners don't know what to look for, let alone how to treat it.

Don't underestimate the range and severity of effects that can be induced by atlas subluxation. Everything is fair game. I've been undergoing NUCCA care for two years, and while it can be a roller coaster, at least it's a roller coaster in the positive direction rather than the other way around, which it was for so many years. If you have any questions about what it's like or how it works, just ask.
