I finally had a hearing test. The doctor concluded there was nothing wrong (physically with my ears). She then said the loss was symmetrical. I challenged this because the left ear is much worse than the right I felt the left ear was at about 40%-60% while the right was 80%+ . After a discussion and a follow-up call from me, she prescribed a short dose of Prednisone. (I resisted because I've had friends on Prednisone who told horror stories.) HOWEVER, within three hours after taking the first dose I could hear substantially better. Throughout the day, the hearing improved. Doctor feel the eustachian tube is swollen and the Prednisone will reduce the swelling. I'll keep you informed
