Drives me mad. It's been like that for years, since I was in my early 20s. The insides of my ears shed loads of skin and are very dry. It's worse at the moment which I think is because of the air-conditioning at work. It regularly flairs up into outer ear infections and can be very itchy. They are also blocked with skin quite often. Bleurgh. I don't have dermatitis or excema anywhere else, so why my ears!?
I don't think there is any remedy - certainly no doctor has ever suggested one other than drops when they are infected.
It's not a big problem in the grand scheme of things, really, just irritating.
Let me know if you've found some wonder cure or have it too!
