I'm a new user here, I figure this is the right place to post after things have happened.
I've had trivial tinnitus for most of my life, I have to assume, because I don't remember a point in my life when I've "heard" silence. I've always had a ringing in my ears, like what I'd imagine a high-frequency noise from a TV would sound like, but there even if the room was technically silent. Maybe I could've picked it up from walking through tunnels with other loud-as-heck schoolchildren who thought it was fun to scream and cause hearing damage. But I digress.
On April 20th I got my first Moderna vaccine. Went fairly well, but a few hours later while playing Star Wars: The Old Republic, I had a brief moment where my right ear suddenly seemed to reduce in hearing before returning along with a new, high-pitched element to my usual tinnitus; enough that it was actually distracting. For a few hours I was distressed, ended up talking to my father — I hadn't known until that moment that he also had tinnitus and wore a hearing aid to mitigate it. His description sounds much worse than mine though (he describes it as being similar to a heart monitor going flat in a hospital drama).
Over the next few days I looked for resources on COVID-19 based tinnitus (already being rattled by the news of Ken Taylor), and started listening to white noise occasionally; I'd already been listening to rainfall sounds using my Google Home speaker, so getting to sleep hasn't been an issue. Eventually it got to a point where I didn't really even notice it was there, especially if I was engaged in any other activity (Twitch streaming, listening to music or podcasts, driving). It wasn't until I was doing nothing when I remembered it was there; and about a week ago it was like I had to concentrate to make sure it was still there. I think I was coming down from it.
Yesterday (or two days ago, technically) I got my second Moderna vaccination. I didn't get any increase in tinnitus for the first twenty-four hours (that I noticed). It wasn't until I woke up and dealt with the more butt-kicking side-effects of the vaccine that I noticed a moderate spike. I'm already about 85% from the body aches, so nothing to worry about that at least; but this spike in tinnitus has me... intrigued, I guess. It's not driving me crazy, so maybe I'm luckier than others. And if I really was recovering from it from the first shot, I have hope that I'll recover from this one too. All the same I think one thing has kept me positive:
As long as I don't lose my hearing so I can't listen to Undertale music, it's not all bad — I can get through this.
