I can understand your concern. By his history and description, possibility of bronchitis is more. Bronchitis causes bronchospasm. And this intern causes cough, chest tightness, sputum production and breathlessness. So better to consult pulmonologist and get done PFT (Pulmonary Function Test). PFT will not only diagnose bronchitis, but it will also tell you about severity of the disease and treatment is based on severity only. He may need inhaled bronchodilators and inhaled corticosteroid. Don't worry he will be alright. Hope I have solved your query. I will be happy to help you further. Thanks. </s>
