Dry cough has always occurred, but there is no expectoration. This kind of patient can be seen in mycoplasma or tracheitis caused by chlamydia infection. This kind of patient can also be seen in some patients with chronic cough, such as cough caused by drugs, such as benazepril or this type of drug, as well as other allergic diseases. For example, repeated coughing may occur after contact with allergens. In addition, there are some dry coughs caused by gastroesophageal reflux disease or postnasal drip syndrome, so you should go to the hospital to check relevant indicators, such as chest CT pulmonary function or blood routine C-reactive protein, mycoplasma antibody, etc., and then relieve the patient's disease, so that the patient's cough symptoms can be alleviated. In addition, the patient should pay attention to light diet and not eat spicy food.
