I've suffered from tinnitus that's gotten worse at times, and for me it definitely feels like there's some sort of nerve that's pinched or damaged because my hearing is totally fine but when certain muscles are tight in the area it gets louder, when I yawn it squeezes something and I get this loud tone, and sometimes it gets worse with pressure or impact. I had a very nasty and loud lower tone but I found physiotherapy around the neck and especially osteopathy around the temporal bone very, very effective in reducing/eliminating that lower tone. Osteopaths will talk about how if the temporal bone is stuck in rotation it can pinch/damage the auditory nerve. I don't fully understand the mechanics but whatever they do WORKS for me in taking away the loudest tone of tinnitus.
