(Concern) I have tinnitus.

Sometimes I hear a faint beeping ultrasound sound when I stay still.

It sounds like about 10 seconds, I can't sleep well or I'm tired.

I think I can hear it.

I had an ENT consultation, and they said there is nothing abnormal.

They say you just need to rest well, but when I hear a ringing sound, my head hurts and I feel foggy like I'm in high altitude.

They say you just need to rest, but it's not easy for a working person to do so, and I'm worried about whether I have to live with tinnitus continuously.
