[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Your fathers x-ray report is suggestive of old healed fibrotic lesions due to previous history of tuberculosis. But in old age reactivation of dormant tb bacilli can occur. And so we need to rule out active tuberculosis in him. So get done sputum examination for AFB (acid fast bacilli-bacteria causing tuberculosis). If this is negative than no need to worry about active tuberculosis. Post infectious bronchitis is also a possibility and coughing is common symptom in it. So get done PFT (Pulmonary Function Test) and if it shows obstructive defect than he may need inhaled bronchodilators and inhaled corticosteroid (ICS). So better to first diagnose yourself and then start appropriate treatment. Hope I have solved your query. Wishing good health to your father. Thanks.
