Then COVID did some sh*t to my sinuses which left them changed.
Now I have relatively low tinnitus in one ear and very noticeable tinnitus in the other ear. The pitch is high... reminiscent to the squeal that an old CRT or tube TV would make if it had no signal.
The tinnitus is some function of my blood circulation, because I can clearly hear my pulse in the worst ear... just this constant pulsing squeal. On occasion it is so loud that I wonder if my head is about to blow open. Blood pressure is good when tested though.
Who knows... that's all so complex and interconnected, and then there's the possibility that some of it is imagined or phantom.
