i am 58 yo, female, caucasian, have a sensation of pressure, emptiness, feather, tickling in my left inner-ear going on for 6 months. the pain is around the upper ear and the neck, down the left arm.
i have seen the ear doctor twice and he cannot see anything wrong. after some reluctance he ordered a CT of the area. the result will be in 3 days from today.
i am scared since the technician asked me a lot about cancer.

Don't let the technician scare you. I hope they find out what's causing it and how to fix it. Feel better soon! :)
