1) i think cold is totally different disease from bronchitis. it is worse than flu.. right?
저는 단순히 감기가 아니라 독감을 넘어서서 기관지염까지 악화 된거 같아요. ( this sentence could explain this situation)
2) 저 지금 기침 많이하고, 콧물 흐르고, 그리고 정말 피곤해요, 오한이 들어요.
in my opinion, Doctor in korea is most well educated so they can understand what you want in English,
몸 조심하세요 ㅜㅜ
