Just been for a hearing test and told my left ear hearing is very good (deaf in right ear). I have problems with noises in left ear and low or high pitched sounds that instantly change like the flick of a switch. Occassionally I experience sharp needle like pains in both ears although never at the same time in both ears. For about three weeks I had been experiencing more dizziness/light headed. The Audiologist said it could be caused by a change in my cerebellum rather than coming from the ears. My blood pressure is high and I am also due for an ECG.
