you have a lot of muscles that go around and connect near the ear. *been there done that* with some ugly problems with nerves.
you have (front, side, and back) neck muscles. then you have multi jaw muscles, and temple muscles, and some muscles at rear of skull. along with some sinus/noise and eye muscles that reach back some towards the ear.
any of these muscles if worn out and tensed up can cause other muscles near by them to start taking a hit and start tensing up. different muscle and combinations of them. can tweek a persons sense of hearing.
hopefully the ENT, as part of your diagnoses. will finger/touch various muscles, and ask if anything is sore or any slight pain or like. along with sensation test. pressing harder or softer to using different tools and rub across skin. to see if you feel things differently.
