I had it and recovered from it quite quickly. It’s just letting your brain hear the sounds and not shrinking or trying to cover your ears from it and in time - you brain will adjust to sounds correctly again. I am no doctor though- discuss with your Gp. It will ramp up anxiety naturally as every sound will suddenly be like an alarm bell to your brain- but just tell your brain it’s ok and it will stop reacting to it.

i have tinnitus - permanent and constantly there. At first it sounded so loud and ramped up my anxiety - but after a while my brain got used to it and filters it out as irrelevant noise so I have to try to listen to it now x
