@hellomiakoda I can relate with that with my tinnitus, one night I've woken up without about 70% less of my hearing, luckily it was temporary, probably mostly related with my wisdom teeth under pressure during the night (before removing those) and the issue I had after the last flight months ago (that took me about 2 moths to recover), and I can recall when I was a kid with the constant otitis that I got every year.
For the moment I'm way better, but I can relate so much with people that have some hearing issues.
