You have dry throat and phlegm, which is considered as an unwell symptom caused by excessive internal heat. I suggest you pay attention to drinking more water.

Suggestion:

I suggest you drink more water, eat more fruits and vegetables, and abstain from spicy food. You can take roxithromycin, Huanglian Shangqing Tablet, Qingyan Tablet and Li Yanling under the guidance of a doctor. At the same time, you can soak the boat-fruited Sterculia in water, eat as many fruits and vegetables as possible, such as apples, oranges and tomatoes, and drink more water.
