Has yours been improving at all? Mine started (just in the left ear) about 48hrs after my 3rd Pfizer shot and remained loud for ~8months. Several months of noticeable dissipation followed by true silence at about the 1-year mark. Thought I was in the clear but it's started again out of nowhere this fall. I'm optimistic it will improve again and can probably be controlled with better lifestyle habits but at this stage is something I feel I will be managing forever. I've seen ENT's and audiologists but they're unable to help past confirming my inner ear and hearing are fine. In 2022 John Stewart had some infectious disease experts on his podcast and one of the epidemiologists stated that he got tinnitus from his 2nd vaccine, and his 3rd exacerbated it. It was at that point that I realized it had to be somewhat common.
It got noticeably milder after consuming medicinal mushrooms (lion's mane etc) for some months but it never went completely away.
I have days where it gets a bit worse. Maybe if I don't sleep well or recently I had some torticolis (neck pain) and had to take muscle relaxers. But then I go back to baseline.
