I would also caution you away from your "can't fix this" I came down with tinnitus and basically did the whole. This is a disaster... for about three months. But then it went away. Then it came back.. I have come to conclude it only happens in the winter and I am not sure why. It seems to possibly be related to weather. My doctors were absolutely useless and seemed to just want me to accept it. Now that it have shared with them that it seems to go away, they don't like that as it doesn't fit with the story. I am plainly on my own.

Another theory I have is that it could be related to dehydration and perhaps that makes my ears dryer and more sensitive. One reason I think that is that it seems to be around in January -March but starts to go away in the warmer / more humid weather of spring, summer and fall
