For years now, I have experienced occasional ringing in my ears. It is usually my left ear though. In the last year or so, it seems it's gotten worse. The ringing will come suddenly, and be very high pitched. And while the ringing is going on, i go almost completely deaf in that ear. Then after about 20 secs or so (sometimes longer), the ringing goes away, and my hearing comes back slowly.
Does anyone else ever experience this? Is this normal?
