Two nights ago I had a ringing in my ear, it lasted for about a minute and then just stopped. I didn't think much about it until the next morning when everything sounded dull in my ears, it got better as the day went on but today It went back to square one, but this time only in my left ear. Even now as I write this my left ear is giving off a quiet ring.
What should I do /adv/?
Could be tinnitus possibly?
