about 4 months ago I started feeling a lot of pressure in my left ear and sinus area. I have lost nearly all my hearing in that ear and a ringing that I never had. I went to a ENT dr. he examined me and hearing test. He said my inner ear wasn’t responding and put me on steroids for 7 days, that didn’t help. I had a MRI he said everything looked normal. This is driving me nuts is there anything else that can be done?
