There are many causes of tinnitus. The Veterans Administration pays out the most in disability to tinnitus. If there was a cure for the nerve damage caused by loud noise and explosions they would be the ones find a “cure”.I think most of these treatments are snake oil or scheme to get research monies.
Tinnitus is a malady that can’t be directly proven. No one else hears your noises.
The US government also pays out humongous amounts for PTSD, which is also just in your head.
Because it’s just in your head, you can’t objectively prove anything does anything, except for what someone says themselves.
People experiencing such maladies are both the judge and the plaintive on the problem. The US government is on the other side, guilty, until proven innocent.
Now, you tell me what is likely to happen with anything that cures someone of something only in their head, when they also lose their disability.
I’m not saying most don’t have tinnitus, but saying US government payouts proves it, is crazy.
