if I approached my GP and demanded the Parkinson's stimulation treatment to cure my Tinnitus, they would most likely laugh me out of there.
@Harley -- I'm sure you're correct on that one, or at least 99% correct. However, you never know when you'll run across a health care practitioner with an open mind, and would consider it; especially if the tinnitus is severe and a person is considering suicide.
As far as "resetting" the brain however; here's a story that I feel has some relevance. -- I've long been into all kinds of so called "alternative" therapies (for decades), and have read several books on reflexology. One story from one of those booksd has stayed with me from all those years ago.
A woman with serious heart issues was getting regular reflexology treatments on her feet. Whenever the therapist would press on the areas of the feet corresponding to the heart, the woman would go into agony, and plead for relief. The therapist would go easy on her, but after a few sessions, the therapist finally said that it was time to go in a little deeper.
After the "deeper" session was underway, the patient at one point let out a loud shriek. The practitioner of course was pretty taken back by that, and wanted to know what had happened. The woman related that she all of a sudden experienced what felt like a bolt of lightning going from her foot to her heart; and then it quickly faded. But the crux of the story is that after this experience, this woman no longer had any heart problems. Something about getting the nerve energy in her heart area unblocked turned out to be key for her.
I've thought of this often since getting tinnitus early last year, because like you, I often think of doing what I can to "reset" my brain and/or auditory system. And I continue to think it's possible. Instead of something like Electroshock Therapy however, I tend to think in terms of long-term "persuasion", such as daily mHBOT. daily self-acupuncture, daily self-massage, especially around the ears and neck, and much more.
Another possible reset therapy that I think holds a lot of potential is intermittent fasting. I ran across a book many years ago that was written by a chiropractor back in the 1950's. He routinely put his patients on fasts, ranging anywhere from 7 to 21 days. He x-rayed their spines while they fasted, and was able to document many severe cases of scoliosis straightening out almost completely. Who'd a thunk it?
I did about a 44-hour fast several months ago, and had a rather extraordinary experience take place in my inner ear (right side). I was doing a relaxation technique (Egoscue Tower), and all of a sudden it felt like a mini-explosion went off in my ear. It jerked the whole right side of my upper body at the same time. I was hoping it would affect my tinnitus, but alas, it didn't.
When something like this happens while fasting however, I take it as a sign my body is trying to do some kind of corrective healing, and I put NO limits on how much progress can be made. I haven't done a fast that long since then, but as I build up more and more resilience with my intermittent fasting, I anticipate doing so. Perhaps even getting up to 7 days or more. But I wouldn't do it without doing supportive detox therapies, and various kinds of other therapies like self-acupuncture to make the process a whole lot more tolerable and enjoyable.
