Two months after lung nodule surgery and still coughing, but chest CT, nuclear magnetic and other tests have no obvious abnormalities, the patient does not have other clinical symptoms, is generally normal; if the imaging examination found that the disease has progressed, cough, hemoptysis and other clinical manifestations, this situation is not normal. 1. Normal: coughing after lung nodule surgery may be due to surgical damage to the local tissues of the lungs, resulting in tissue cell secretion of mucus or inflammatory secretion exudation, stimulation of the trachea and bronchial spasm, causing coughing. If the cough is not serious, and there is no obvious abnormality in chest CT, MRI and other examinations, this situation is generally normal. 2. Abnormal: patients with severe coughing symptoms, accompanied by sputum with blood, hemoptysis and other clinical symptoms, lung imaging found that the nodule recurrence or tumor occupancy, this situation is not normal, and patients need to be early for systematic examination and treatment. Two months after the lung nodule surgery, patients should be reviewed regularly to observe whether there are other clinical manifestations and pay attention to the progress of the disease. If any abnormality is found, consult a doctor as soon as possible to clarify the cause of the disease and treat it actively. Do not delay the disease, so as not to miss the best time for treatment.
