I up for giving it a try, but don’t have high hopes.
There are apparently many caused of tinnitus, some involving nerves and some involving physical damage to the ears, usually from high noise exposure (mine I know is related to firing guns without earplugs, working around hot rods with open headers without earplugs, and working around both recip and jet engines without earplugs - all in my stupid youth).
From what I’ve been told by several doctors, if you have the physical damage, you may as well learn to live with it because it ain’t going away.
I once had doctors in an emergency room tell me after I dove off the roof into the backyard swimming pool and pranged my back but good (all in my stupid youth ...! But at least I used the butts of cigarettes as earplugs when I went shooting! ;^) ... that I had strained my back and would not be able to do anything but lie down for at least a week. Went to a chiropractor the next day and was waiting tables that night.
Just sayin ...
