In life, patients with irritating cough in the throat generally consider the following aspects: I. Patients are likely to have inflammation in the pharynx, such as having acute pharyngitis or acute laryngitis or acute tonsillitis, which are prone to produce irritating cough. Second, the patient is likely to have allergic symptoms to certain foods or items, and the edema of the mucous membrane in the pharyngeal cavity will obviously cause an obvious itching sensation, so an irritating cough will occur. Third, the patient is likely to be infected by bacteria or viruses, forming bronchitis or pneumonia, and the patient will develop an irritating cough. Regardless of which of the above causes is triggered, active examination and symptomatic treatment are needed for the patient’s condition to improve, and he or she must exercise more to strengthen their resistance.
