Two years ago, I experienced Sudden Sensorineural Hearing Loss (SSNHL), and am now almost completely deaf in one ear. This year, one of my colleagues had the same thing. Now I see there's a study out showing a strong correlation between COVID and SSNHL.
I guess that explains a lot. But, shit.
BTW If you find you suddenly lose hearing in one ear, get yourself to a specialist *immediately*. You have a 24-36 hour window to save your hearing before it becomes permanent.
