I have tinnitus.
Old people tend to get it, but sometime younger punks do, too.
Oh, what is it? Sorry, couldn't hear the question.
My tinnitus is a constant buzzing in my ears. My left ear is worse than my right. Sometimes the buzzing becomes a high-pitched whine. Every now and again, I can even hear my heart pushing blood through my body--this bothers me, since I suspect it's one of the signs of an eminent stroke. Luckily, my blood pressure is normal, but this does freak me out a little bit.
Personally, I think it's due to all those years in a lab listening to the machines and centrifuges whirring away.
I just started taking something that hopefully will make it go away. I'll let you know in about 6 months or so.
