Ow! My tinnitus!
Mawp... Mawp!
I've been dealing with it for, ~20 years
You know that ancient 90s alarm clock radio stashed in your basement? Put it on AM, turn it to the upper end of the dial where there's no stations (lower end tends to have a lot of sporadic noise from appliances and electric fields) and put it on a barely audible volume. Instant white noise generator.
Weirdly enough, that's kind of how I found out I had tinnitus. I had my headphones on and got bothered with the high pitch static sound, but when I went to unplug it, I found it wasn't even connected to any device.
I think this is just a you thing. My ears don't make noises when I'm trying to sleep
Mine do, and when I'm not falling asleep... I hate tinnitus
Have you tried unplugging any chargers or electronics? Thought I had tinnitus for the longest time, until I realized the sound was coming from my outlet, and unplugging the brick solved the problem.
You should watch the new Blackberry movie if you haven't. I promise the relevance of this comment makes sense if you've seen it.
I seriously want a version of this video with floofy screaming cowboy cats now.
(and yes, OP please look into tinnitus.)
