[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. There are two possibilities in your case. 1. Non resolving chest infection 2. Post infectious bronchitis. So better to 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 chest infection. PFT is needed for the diagnosis of bronchitis. You may need antibiotics, inhaled bronchodilators and inhaled corticosteroid (ICS). So better to first diagnose yourself and then start appropriate treatment. Hope I have solved your query. Wish you good health. Thanks.
