Is there a good place to get ENT surgery in Dongtan or Suwon?

My child has been going to the hospital for two months and is taking antibiotics.

I'm worried because I've been taking it for two months.

I'm fine only when I take antibiotics, but if I don't take the medicine, my nose starts running right away.

I have a cough and my eyes are covered in yellow mucus like snot.

I've been to three or four hospitals, but there's no improvement. Is there a hospital that treats my nose well?
