Patient: I have taken both Chinese and Western medicines with no obvious effect I have done pulmonary function respiratory in Shanghai, normal Laboratory and examination results: X-ray and CT are both increased texture in both lungs and bronchitis, I was asked to do bronchoscopy, which I did not do. I never cough when I sleep. I cough in the morning, and I cough more during the day, about 2-3 times per minute, sometimes with chest tightness, mainly dry cough, no phlegm, and I cough more during the day, but I don’t cough as soon as I get into bed and lie down for about 10 minutes, and if I wear more clothes, my cough is better. Fear of cold. Allergic cough. Patient: I have no history of allergies, perhaps because I have not checked for allergens, so it should not be an allergic cough. It’s just a dry cough, regardless of location, and it’s the same indoors and outdoors. Because of my reflux gastritis and gallstones, I am more afraid of the cold this year than in previous years.
