Maybe it's related to the brain damage part: COVID didn't just kill my sense of taste and smell, but changed how I perceived touch too. Touch on my skin felt like I had a thin layer of something on my skin, even my teeth. It went away the same time I recovered my taste and smell. https://twitter.com/esesci/status/1608553863937921025?s=20

I didn't notice anything unusual about my hearing though.
