Is there a renowned internist?

It's a second-grade child with sinusitis. At first, he was going to the hospital for rhinitis.

I caught a cold and kept feeling sick, which led to sinusitis.

I have been going to the hospital for several months, taking medication, and I recovered last week.

I went to the hospital because I had a fever, and they said I have bronchitis, so I took more medicine.

I went to the hospital today and they said I have sinusitis again.

Because the child is sick, I can't focus on work and it's very difficult.

Are there any ENT clinics in Dongtan or Suwon that specialize in sinusitis?
