Fibrous foci in the right lung may be related to lung inflammation and interstitial fibrosis, which can be treated by drugs and surgery, and the specific treatment effect varies from person to person. Fibrous foci can be produced by lung tissue damage after lung inflammation, without uncomfortable symptoms, usually no treatment is needed, and antibiotics can be applied if there is cough and sputum. Pulmonary fibrosis is a group of diffuse lung diseases that lead to the loss of alveolar-capillary functional units. Typical symptoms are chest tightness, dry cough and dyspnea. Commonly used drugs include the bronchodilator terbutaline sulfate, the antifibrotic pirfenidone, the cough suppressant dextromethorphan hydrobromide syrup, and, in the acute phase, hormones. Lung transplantation is mainly indicated for patients with advanced pulmonary fibrosis. If you find the right lung fibrotic foci, you should consult a doctor in time, under the guidance of the doctor’s treatment, not unauthorized use of medication, so as not to delay the condition. Pay attention to rest on weekdays, quit smoking and drinking, and keep a regular routine.
