With turmeric, make sure to eat/take black pepper with it, or if taking a pill, make sure it has piperine (which is in black pepper).
The piperine greatly increases the absorption of the turmeric. Note that this is NOT a cure and probably won't make a significant difference in your ringing. However, turmeric is very, very anti-inflammatory and can help with any damage that might have occurred and in general is good for overall health, so it can't hurt.
Unfortunately no one will have an answer for you because everyone's ears, genetics, backgrounds, causes, symptoms, etc. are different. Some people get better after a few days (they're the lucky ones), some people months, even YEARS, and for some very unlucky souls, it's with them for life. The more you search for answers, the more disappointed you'll be. This sounds cliche but you have to take it one day at a time and appreciate what you have now. If you start counting the days, or get your hopes up too high if you find a "cure" online, your anxiety will just get worse. I know because that's what I was doing a few weeks ago. But I understand being upset, it's a terrible thing and none of us deserve this
.
Also unfortunately, I thought I was getting better but the past 3 days it seems louder. I think fluctuations are normal, even if I can't identify a trigger. But they definitely throw me off and has started giving me anxiety again :/
Also remember that it's technically NOT a sound—it's your brain projecting noise to make up for the damage done at whatever frequencies.
Reminding myself of that has helped with habituation. It gives me some hope that my brain will eventually filter out the noise. I hope that makes sense and can help change your perspective
