I have had tinnitus for about 2 years now and recently, after exposure to a loud noise (video game room), it has gotten worse. Used to be primarily in my right ear, now it is even louder in the left ear with a high-pitch whining sound.. have not been able to sleep for the last week (sigh). I went to 2 ENT's who, as others have said, basically told me that I have to learn to live with it. Do the masking devices really work? And can you really stop using them after 2 years? ($1500/year is quite expensive)..any help is greatly appreciated..starting to become unglued here...thx!!
