I had a cold, sore throat, and mucus running down the back of my throat. I was debating between internal medicine and ENT, and ended up going to the ENT clinic. I remember hearing in passing that Yonsei University's Best ENT Clinic was known for its excellent treatment. My first impression of the hospital was that it was surprisingly large and clean. The wait was long due to the large number of people. There were quite a few children waiting to be seen. (I was a bit surprised that I came to the ENT clinic instead of the pediatrics clinic.) Anyway, the doctor was kind and calm, explaining everything clearly and giving me thorough treatment. It wasn't a quick treatment, but that actually made me trust him more. I recovered quickly after taking the prescribed medication for two days.
