I have ringing in my ears. Or a high pitch tone. It sounds like the highest tone i can hear. It's there when it' s quiet. I don't know if i always had that tone. i think it's new. I wear earphones without listning to music right now and can hear the constant tone clearly. I worked with heavy machinery but this was a long time ago. I went clubbing a lot and visited festivals, also a long time ago. There was a high volume techno beat in clubs and at festivals and i've been close to the speakers... i think i screwed up my hearing.
I don't feel bad yet because it's not disturbing. Hopefully it doesn't get worse.
