(Concern) If sinusitis is severe, do dark circles also become worse??

The child has a runny nose because they resemble me.

I thought I had severe dark circles because I was tired.

According to my search, it says that if you have rhinitis, dark circles can develop...

There is nothing specific currently requiring hospital treatment.

There is nothing to take medication for.

How is rhinitis treatment typically conducted at the ENT clinic?

Does consistent treatment for rhinitis improve the condition?
