Sometimes I hear a ringing sound in my ear.

Because the place I work is on-site.

I think we can't ignore that effect either..

I am only guessing the cause for now.

I understand the opinions of doctors who only say it's okay to visit the ENT department, but

Still, I guess I can't help but worryㅠ

I'm also curious if there are others who are experiencing the same thing as me..

Let's all stay healthy.
