anecdote for anyone else reading about Covid related tinnitus - I've had hearing damage related tinnitus for a decade. Got Covid in April '22 which caused my existing tinnitus to 2-3x in severity, lasting a couple months before it either reverted to baseline or I got used to the new normal. Very scary experience. The CEO of Texas Roadhouse famously committed suicide due in part to severe post-Covid tinnitus.

For anyone struggling to cope with Tinnitus out there, one thing that has helped me immensely is Zen meditation. Doesn't make it go away, but builds up a control over attention with which you can cope much better.
