Seeems to get worse when I have allergies or sinus pressure. I wish I knew how to stop it as it drives me nuts and creates anxiety.I can get it to change volume with a loud noise near my ear such as a hair dryer. DR's say live with it. I have researched it but found nothing that helps. I see there are products to stop it but I am skeptical and have thrown money at enough things that don't work. I used to enjoy the silence but it has been years now since I have enjoyed it for more than a few days at a time.I have been able to accept many things with fibro/fatigue but this one still gets to me. Anyone else?
