I have fluctuating hearing loss , low frequency loss. Low salt diet , diuretics, prednisone make no difference. I have constant tinnitus of varying levels. EENT ruling out Meniere s, Audiology doctor says not Meniere s. What can this be? I am SO frustrated. Started September 9th. History of flying August 25 and 26th, cold symptoms after flight. Got a dog.... allergies??
