I have to concur with Batty...it may be frustrating, but symptoms and side and size seem to have no correlation between people. My symptoms are 16% hearing in my right ear, tinnitus, and some feeling of fullness in my ear some days...not all days. I remember seeing someone mention a quick searing pain in the ear, and that happens to me maybe once a year, but I never thought anything of it because I get that in various points of my body on occasion. Those are my only symptoms...so you'd think I'd have a small AN, right? It's 3.1 cm, not so small. The doctors seem truly shocked I have no other symptoms. I'm not dizzy, I don't have vertigo, I have full facial function, nothing's dry. I used to get migraines in my twenties, but in the last 10 or so years, I only get tension headaches...so maybe the AN is keeping me from having migraines? I know this info doesn't give you anything solid to work from, but I think that's the one commonality we have...each AN is different.
