[kaisersouse]

I get it from time to time. I have limited hearing due to massive ear infections from the age of 2 till about 17. I've also had my eardrums ruptured a couple times as well since then. Sometimes I'll get the high-pitched squealing in one of my ears, I just ignore it until it goes away. I expect to have this as a chronic issue when I get older.

See a doctor, but I don't think there is a lot they can do. Your best bet is to try and 'retrain' your brain to ignore the noise (filter it out).
