So, whatever my particular brand of tinnitus is, it's influenced by positions of my jaw. My theory is that a bad car accident with whiplash and a concussion caused a cascade of minor to severe health issues that inhibit my body's natural healing forces (e.g. no stage 3 sleep to build T-cells and integrate short term memory).
One cause of tinnitus is a blood vein/artery, I can’t remember which, that runs too close to the surface near the eardrum. It can be fixed with surgery, but is very expensive and dangerous to boot.........
