Symptoms from lack of exercise and frequent long hours of sitting for many years.

I gradually developed symptoms in this order:

TMJ (had occasional jaw clicking prior to start of tinnitus, which later got a bit more apparent)
Tinnitus
Eye floaters
Hearing sensitivity
Blurry vision
Tinnitus became more reactive to movement of jaw/neck/ applying pressure on sides of head.
hear some clicking at back of neck when doing chin tuck, or at the jaw?
clicking behind the back/shoulders when shoulder squeeze.
later on it progressed so badly, that sitting with poor posture would spike tinnitus or just laying in bed and applying pressure on head.
(More recently and temporarily like for 3-4 days) SINUS pressure, eyes tearing up. And a lot of jaw/internal head pressure. (you know what i mean by that if you got it, as in if you hold your stomach in, if you feel instanteous pressure build up at the throat/head/jaw area) (THIS WAS INSTANTLY RELIVED AND HELPED THROUGH EXERCISING AGAIN)

What helped:

Be conscious of your clenching, sometimes unclench teeth if you notice you clenching or doing it at sleep or sat at pc, etc.

EXERCISE IS AS SIMPLE AS THIS (2-3x a week):
