Not sure if this is already a topic.
So, do you have it? If you don't know what it is: there are different sounds different people hear but if you've ever been to a gig and had that ringing noise afterwards, just imagine that but for the rest of your life. Use Google or Wikipedia for a better explanation.
I went to a lot of concerts when I was younger and always listened to my music on the highest volume for years. I remember after a concert the ringing noise would go away after a few days, but one time it ended up staying for longer than I expected, and I still carried on listening to my music too loud. It was only after it wouldn't go away that I ended up finding out I had it, and the fact that there's no official cure for it yet really scared me. I'm used to it now but on some nights when I'm trying to sleep it's really irritating and it feels like I'm going to go insane.
But I can live with it. In the end I did it to myself. People were always telling me to not listen to it too loud otherwise it would damage my ears, and being younger I was oblivious and ignored the advice. They should really emphasise it to people, because it's fucking annoying hearing it all day.
Here's an interesting section from wikipedia on tinnitus highlighting notable people with it:
