Hi - my doctor said to test my hearing using the Uhear app when I am having an attack and to call if it gets worse rapidly over a week. Has anyone else ever been told to use an app? During an attack over a week I can see my hearing deteriorating a little every day in the bad ear which is upsetting. Then all of a sudden my ear will clear instantly and my hearing comes back. Have had 7 attacks so far with hearing returning each time but at some point my hearing loss will be permanent - correct? For how long do others experience attacks? A week, two weeks?
