Have a loss of hearing in left ear. Have fullness feeling also. Had ENG, all hearing tests, and balance test.Sometimes i will get a popping sound as though I'm on an airplane. Got tested for vertigo, etc. I can move suddenly or turn my head backwards and get dizzy to the point of getting nautious.Tests all but ruled out a neuroma, had cat scan of left ear but not full head MRI. Does anyone have any similar symptons? If so, please contact me, the doctors don't seem to know whats going on. Just want to make sure there is no underlaying problem. Thanks!
