<bot>: Thanks for your question on Chat Doctor. I can understand your concern. You are having chronic cough (cough for more than 2 weeks). So we should definitely rule out lung infection (pneumonia or tuberculosis) and bronchitis in your case. So consult pulmonologist and get done clinical examination of respiratory system, chest x-ray and PFT (Pulmonary Function Test). Chest x-ray is needed to rule out lung infection. Put is must for the diagnosis of bronchitis. You may nerd antibiotics, inhaled bronchodilators and inhaled corticosteroid based on diagnosis. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
