I recommend the Malgeun ENT Clinic in Jungnang-gu.

When you have a cold or runny nose, you go to an internal medicine doctor or an otolaryngologist.

For experience and colds, I felt that ENT was more effective than internal medicine.

While I was there, I discovered this place not far from my house. It's relatively new, so it's clean.

The doctors and nurses are all friendly, and the treatment seems to be quite effective.

A family member had something similar to an allergy that made him have a strange runny nose, and no matter where he went, there was no improvement.

I'm quite satisfied with this place.

I recommend the Clear ENT Clinic in Jungnang-gu. It's located at the entrance to Dongbu Market, across from Jungnang Station.
