Does it get louder when you clench your jaw? Sometimes tinnitus is due to teeth/jaw issues. Sometimes people report tinnitus getting worse or better after getting teeth removed or jaw work done. For a variety of reasons, I'm starting to think my ringing is at least partially due to pressure on my teeth and jaw. Now I need to find a TMJ specialist who will be willing to try to figure out what might help.
That's an interesting observation! Yes, it does, and it's a higher pitch.
That might be something to explore; thank you for that. I also grind my teeth aggressively at night (which I wasn't aware of until ~1y ago when my wife told me).
