So, I've just come from Harley Street in London, having just had an appointment with the UK's and probably the world's leading ENT Doctor.
And he told me that tinnitus volume as long as there is no current infection is always at 20 dB and the perceived loudness is always related to emotional perception and stress towards it.
And given the right frame of mind everyone can habituate/return to silence/near silence.
I can only say that you have a lot to learn, and i advise to always check every advise twice and compare it to experience of other sufferers and every scientific paper you can find. Learn from other mistakes and don't take opinions from one source as truth, that what research is about.
My mistake was listening to ENT 7 years ago that I shouldn't go to a hospital after acquiring tinnitus because of headphones (well, she said that as 13 year old back then I can't have tinnitus and that I simulate it. She said that I'm too young to have it. It makes my angry even now.), and just wait for it to tune out itself. Well it was the first hour of tinnitus so if I would get steroids at hospital back then, today I could be tinnitus and hyperacusis free. It also got worse because I didn't know that you have to protect your ears especially if your tinnitus is from noise exposure, every ENT also told me not worry about it and live as usual. I developed hyperacusis after more and more loud situations and trusting others.
From now on I trust only myself and my own research based on what trusted researchers says, what other sufferers says and what we will learn in the future but biggest factor is my own experience to not make things worse (it at least delays it as much as I can...)
I would happily trust some ENT or neurologist or someone, it's not that I don't like doctors. I have some serious diseases and good doctors to keep their progression in check, but they don't have a clue about tinnitus and they don't lie to me that they have. That makes me trust them more because they just aren't lying. They trust me with my tinnitus and what makes mine worse, and I trust them that based on my experience they will try to not make me any harm with meds etc.
Personally I would never listen to that ENT of yours again after he said something like this. Literally every experienced sufferer and every experienced researcher / doctor IN TINNITUS FIELD would laugh after hearing this.
Permanent spikes, has he heard about those? It's not something that is tied to emotional perception...
It's up to you what you will do, but take care and please check every advice twice with as many trusted sources as you can. You can learn from my own mistakes above.
