Hi Sophie,
Just wanted to say I'm in the same boat as you: 25 and imagining how this is going to impact my life once the world goes back to normal if the tinnitus doesn't go away (concerts, movies, hell even going to a baseball game worries me). Mine also started from an ear infection, with the ringing starting back on December 1st, and while I say it has gotten better, it's still very much there. Like yours, it gets worse when watching TV/listening to music a bit too loud and is better in a quiet room.
Would you say that, since this started, it's gotten better/reduced in volume? If so, try and remind yourself that while yes, the noise is still there, it's much better than it
was. If it's still the exact same as when it started, you may want to see a doctor to have them check if the infection is lingering and that may be why there have been no improvements. I've noticed that mine seems to have gone from a true ringing, to a buzz, and now is more of an electrical hiss noise. Has your noise changed at all?
Have you also looked into things that might make it worse/spike it? For me, that was taking Aleve or Sudafed, as well as drinking regular soda (I usually do diet, but really needed the sugar to stay awake at work!). It was horrible for about a day and a half before it went back down to its "normal" level. Try and track if you have any triggers aside from noise.
As someone told me when I made my first post on here, this is going to be a bit of a rollercoaster while your ear recovers. There will be good days and bad days. Just yesterday, I could barely hear it all day and thought "holy shit, is it finally done??" while today I think it was tripped by the music in the car being a little too loud on the way to work, so it's been buzzing more. Being back in my quiet office has calmed it down again, though, which is a relief. I'm realizing that my tinnitus has been reactive since December, and the sensitivity has calmed down, so maybe in a few more weeks' time yours should calm down as well?
I'm sure you're sick of reading/hearing this, but time is your friend here. Just try and stay positive, as lame as that is!
