I m always hearing a high pitched sound in my left ear. It has been 3 or 4 months since I have this problem. Its irritating and is audible at nights before sleeping. I m a musician and so i was a consistant user of headphones but now I have stopped the use of it. Now a days any loud sound feels too loud and I'm not able to bear any loud sounds for e.g. the whistle of a pressure cooker. Please help me some sort of advice.
