Thanks for your question on Healthcare Magic. I can understand your concern. By your history and description, possibility of post infectious bronchitis is more likely. Bronchitis (inflammation of airways) is common after respiratory infections and is known to cause prolonged coughing, chest pain, tightness etc. So you will need inhaled bronchodilators (formoterol or salmeterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone) for bronchitis. Consult pulmonologist and start above treatment. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
