ENT

Whenever I eat something, I keep getting a runny nose, and a lot of it. I think it's because I got the wrong rhinitis treatment at an ENT clinic before, but my nose keeps running. I don't know why, so I think I need to go to the hospital again. Are there any good hospitals in Seoul?

If there is a good hospital in Gangnam-gu, Gwangjin-gu, or Gangbuk-gu, please let me know.
