Hi, and thanks. I'm 77 years old, in relatively good health. I have one hearing aid in the only ear I can hear through - my right one. Have had the aid for several years after losing the hearing in my left ear. In the last few days I have experienced dizziness, and occasionally, only occasionally, have a touch of vertigo. But it doesn't last but a few seconds after I focus on a single object in the room. About three hours ago, a sound appeared in my non-listening ear, the left. It's like air rushing. Of course I cannot hear in that ear, so putting my hand over it makes no difference. Any ideas of what to do?
