Tinnitus

@handymann  have you been examined by an ENT? Ever had a hearing test by an audiologist?
I'm glad I did since they were able to reduce my tinnitus episodes.

Steve (Handymann), I think you may be referring to hyperacusis.  And to posts by member "Giri," a neurologist who mentioned that disorder in two posts in the following thread:

@handymann - I too have the ringing (first noticed at five years old). I also have hypertension. The noise seems to be loudest (never severe) when my BP is up there. Might be worth investing in a BP "Cuff" and take readings when you have episodes...

Same here. Always had a little ringing thanks to flying lessons without headphones when in my early twenties. A couple of years ago the ringing got worse and the doctor recommended steroids. No thanks. My chiropractor said is was a result of the neck injury he was treating me for. He pointed out that since the ringing varied with me moving my jaw out, it was caused by the upper neck bone putting pressure on the nerve. After two years of regular treatment (neck adjustment), the ringing is back to where it normally was.

I’m no doctor but if your ringing changes with extreme jaw movement, then a chiropractor may be helpful.

My hyperacusis and tinnitus is fairly well controlled now after years of suffering. 
Hyperacusis is a sensitivity to high frequencies that can result in pain. It took a very long time to put together an audio rig where music is presented in a realistic and organic manner.
