A buzzing in my ear: What is tinnitus?

For some people, tinnitus is a terrible inconvenience that can cause them to take medical leave, have sleepless nights, or suffer psychological distress. — Filepic

I have been having this buzzing noise in my ear since yesterday. I have never had it before. At first, I thought an insect was trapped inside my ear. What is this buzzing noise?

This buzzing noise is called tinnitus. It is pronounced as TIN-ih-tus. It is actually the perception (not real) of a noise in your ears. Some people hear ringing, clipping, hissing, chirping, roaring, whistling, or even other sounds instead.
