Recently, the number of colds has increased, especially among young children, and every major hospital is full of pediatricians. Many people have coughs after getting well from colds but they do not get well easily, and some even cough all night long, affecting not only their sleep, but also their families. I once treated a patient who had a cough for 3 months and still didn’t get well. After consultation, I found that it was just a dry cough without phlegm, caused by airway sensitivity, and was prescribed 3 doses of Chinese medicine and supplemented with vitamin C and Zn. You should avoid wind and run less in autumn and winter, especially when running in high winds. More attention should be paid when coughing. Generally cough after cold only needs 2 – 3 days of treatment to be cured.
