The warm treatment I received at Yonsei Michorom Hospital when I suffered from a cough every night in Seoul

I had a bad cough at night, so I went to the hospital. It wasn't a cold, but I was worried because I just had a cough and some phlegm, but they said there wasn't anything particularly wrong, so I got some tests done just in case, and since there didn't seem to be anything wrong, I got a prescription for medicine, and decided to just get some more treatment and take the medicine, and I'm relieved to see that I'm getting better. They said that my immunity has also dropped a bit, and that it would be good to keep my throat warm, and that I should drink lukewarm water often and it would get better, so I'll just have to keep getting treatment. The doctor was very kind and thorough in his treatment, and the nurse was also very friendly, which was nice.
