My upper body update.
While x-rays have come back normal. I do believe though that I have cervical instability especially on the left side. However, deep neck muscle strengthening, lower core, and arm strengthening are probably what I need to try first.

Deep neck flexors - IMO - dysfunctional (L especially); still figuring out how t strengthen these.
Tight Pec Minor (R>L)
Tight Lats (R>L) - perhaps stretches for both pec and lats might help

Probably aloe vera to reduce the load of inflammation induced by stretches.

Prolotherapy is probably my last option to fix my posterior ligaments. I suspect lax ligaments allow my neck to translate forward when sitting forcing my pec minor and levator and upper traps to get overactive.
