It is impossible to say, really. A lot of people have experienced
ringing in their ears for up to several weeks, before it suddenly
disappeared again. I'd wait a few weeks if I were you, to see if it
disappears by itself, which it might very well do.

My first T actually disappeared within two weeks. It was the result of
loud music. I was foolish enough to go to another place with loud
music after it had disappeared after the first time, and it returned
again, and now it's been there for several months.

But yours might well go away - you'll just have to wait and see.

Do you know why the ringing started?
