Thanks for your question on Chat Doctor. I can understand your situation and problem. You are having breathlessness on exertion, and now it has been worsened and also associated with cough. So possibility of bronchitis is more. 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 other lung conditions like pneumonia. PFT is needed to rule out bronchitis. It will also tell you about severity of the disease. You may need inhaled bronchodilators and inhaled corticosteroid. So better to first diagnose yourself and then start appropriate treatment. Hope I have solved your query. Wish you good health. Thanks.
