About 6 years ago I caught a bad flu which evolved into an ear infection that required antibiotics, my ears were in pain, really stuffed, popping etc. When I got that under control, I was left with what can only be described as tinnitus, a very high-pitched sound in my ears, almost undetectable in my right ear but quite annoying in my left. It was there for about 12-18 months, but it slowly started to go away to the point I had to pause for a minute to remember if the left/right one was more affected. After 9-12 months I was only able to hear it if I was wearing ear plugs, and now I need to wear ear plugs and really concentrate to realize that it's not 100% silence, but it's close to 1-5% of what it was and even the "tone" of the tinnitus is more muted. I'm not sure if they genuinely healed, if there even is such thing as temporary tinnitus (for more than a day/week), or if my brain just got better at filtering that out.
