Sorry about this. It is really shitty. Like you, I got a case of tinnitus via ear infection. In my case it was caused by a three-week-long infection.

However, I count myself massively lucky that it did slowly resolve over about 5 years, to the point where I’d now consider it nearly gone.

I know it’s easy to lose hope, and get really frustrated by it, but I hope you have good days coming to you. Good luck.
