The reality is that the Internet is often useless for this sort of thing. I, like many others, got back problems during the pandemic. In my case science will mostly tell you to do nothing, health care will give you physical therapy, the Internet is full of instant relief stretches, short workout programs and psychological solutions ("don't care" which plays into "do nothing" like science suggests).

I managed to rehabilitate myself mostly by walking for hundreds of hours. That isn't really some trick or secret. That is what health care would eventually tell you to do. It just isn't reflected as much as the easy and the qualified solutions. Now I got tinnitus a few weeks back and it's the same landscape on the Internet. But getting the information isn't really the problem, it is making use of it. It's easy to find a high level of engagement and it's easy to find a high level of knowledge. The challenge is finding both.

I have always been somewhat sensitive to noise, but a lot of people aren't. They have whining fridges, squeaking doors or noise pollution all over the place. They don't really care. You are dismissing symptom reduction a bit. But as far I can tell that is the solution for most. A combination of stress reduction, lifestyle reform and behavioural therapy, potentially with a hearing aid or noise masking. And then it gets manageable enough that they don't care. Maybe you can do that yourself, but possibly you can't and will conclude that it doesn't work.

Of course like I said you shouldn't trust me. I'm going to go find whatever specialist health care can give me without paying too much extra.
