If you have pulmonary pustules and emphysema, a little numbness and drowsiness in the left chest should be considered as a sign of airway obstruction and hypoxia in the body. Lung blisters refer to the fusion of alveoli in the lung tissue to form air-containing cystic cavities with a diameter of more than 1cm; emphysema refers to the pathological state in which the distal lung tissues are over-inflated due to lesions and degeneration, which leads to an increase in lung capacity. The main symptoms of pulmonary pustules are chest tightness, shortness of breath, etc., and if there is a rupture of pulmonary pustules, there are also chest pain, dyspnea and other hypoxic manifestations; emphysema is mainly exertional dyspnea, i.e., dyspnea occurs as soon as there is an activity, especially in the original cough, coughing up sputum on the basis of the progressive aggravation of dyspnea, and there are also cyanosis and other manifestations of hypoxia. When hypoxia occurs, there may be symptoms such as drowsiness and sensory numbness. Therefore, when there is numbness and drowsiness in pulmonary pustules and emphysema, it is important to consider that it triggers airway obstruction and hypoxia in the body. If chest discomfort occurs, consult a doctor in time, follow the doctor’s instructions for examination and treatment, don’t let it go and miss the condition.
