Thanks for your question on Chat Doctor. I can understand your concern. Yes, you should definitely take him to pulmonologist for chronic cough despite treatment. Possibility of following is more 1. Uncontrolled of worsening bronchitis2. Chronic lung infection like tuberculosis or fungal3. Lung cancer. So better to take him to pulmonologist and get done clinical examination of respiratory system, chest x-ray, PFT and CT thorax to identify the cause for his persistent coughing. Hope I have solved your query. I will be happy to help you further. Wishing good health to your father. Thanks.
