Might be worth looking into neck/shoulder structure (with a PT that's CFMT certified) just to rule out it being an issue with a compressed/tension nerve due to how your neck/shoulder physiology developed.

I saw two different physiatrists, a neurologist, two ENTs, an audiologist, and my GP about the sudden onset tinnitus and they all just shrugged it off. I had a hunch something was going on with my neck because I could modulate the tinnitus a bit with the position of my neck and jaw--I shared this with all of them and they said I was being neurotic. It wasn't until I saw a good PT (she was the third different one I saw) that I was able to get this addressed.
