[Help] I keep obsess over my tinnitus OCD

Quote

I heard ringing sound when I plug in my both ear, in absolute slient, I have this experience since I was a kid

it is not noticeable when I was doing work or having my usual life

I read it somewhere it is known as tinnitus, and most people have it, and it does not have a cure. But now I will check for ringging sound first thing I wake up and lie on my bed

is tinnitus normal for most people?

is tinnitus a problem?

How should I deal with tinnitus OCD?
