Symptoms of lung disease, which is also a symptom of the disease of the whoosh system, are mainly in the following four aspects, first cough, second hemoptysis, third chest pain, and fourth difficulty in whistling. Cough is one of the most common symptoms of respiratory diseases, it is a protective physiological reflex, with the role of removing respiratory secretions and harmful factors, but frequent or severe coughing can cause many complications, such as chest pain, headache, abdominal pain, vomiting, and even urinary incontinence. Hemoptysis is bleeding from the tissues of the throat and any part of the rosy system below the throat, and the blood is expelled through the mouth. The amount of hemoptysis seen clinically may be large or small, but regardless of the amount, it is suggestive of organic pathology. Chest pain is often accompanied by common symptoms of the respiratory system, such as coughing and sputum, and chest pain is often exacerbated by coughing or deep whistling. Difficulty in whistling is a subjective feeling of abnormal and uncomfortable whistling. Difficulty in whistling is both a symptom, i.e., the patient’s subjective feeling of insufficient breath volume and effort in whistling, and a sign, i.e., the objective manifestation of changes in the frequency, depth and rhythm of whistling. Lung disease symptom performance is mainly these four, but specific to different lung diseases, each symptom focus is different, as long as there is a cough, hemoptysis, chest pain, difficulty in whistling and other symptoms, we should consider whistling system disease.
