I’ve dealt with this since I was 4. Fortunately, only occasional bouts.
I had a ear infection that totally destroyed all the little bones in my left ear. Now I have a hunk of plastic in their place.
I don’t have ringing, I here tones, right around 1000 hertz.
It can be quite maddening.
I have those tones too, occasionally, they fade in and out like a tuning fork passing by my head................
