Sorry to hear about your worsening, @RunningMan. Yet some people actually improve, not just habituate. Just as I guess we do not quite understand how the tinnitus/hyperacusis actually happens, we do not understand how it heals.Indeed. My tinnitus is most certainly from noise induced hearing loss, mostly longer term with repeated exposures / trauma and worsening 19 months ago, so there's not much hope for me. I then started experiencing TTTS 3 months ago. And hyperacusis is a more recent development, becoming more obvious about 6 weeks ago. Also terrifying are the posts from people stating they had hyperacusis that later worsened into pain hyperacusis / noxacusis. You realize things are getting worse over a matter of months and can continue to. It's no longer just about living with tinnitus and the anxiety/insomnia/brain fog it brings.
Nerve healing is a thing, it often takes a very long time even in other parts of the body, like limbs. I suppose if there is minor nerve damage, things can heal eventually. Then the brain neuroplasticity on top of it, which probably is highly individual. We just do not know. The way I think is that if that damage is limited, i.e. "hidden hearing loss", healing can happen. The more damage there is, the less likely healing is. All this is speculation.
When it comes to worsening, other factors can be at play, cold, viruses, medications, things that would be of little consequence if it weren't for the ear damage and, resulting brain changes.
Clearly the human body, and especially the brain is so complex. When you break some part, it is thrown off balance, and things tend to malfunction more down the road and also show up in other parts Imperfect analogy, but it is not unlike computers (which are way simpler), where if a component, software or hardware, behaves differently, the effects are often unexpected and can show up seemingly far away from the original location of the problem.
Makes one wonder if we were created out of chaos or made by some intelligent being...
