[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. By your history and description, possibility of bronchitis is more. You are also having history of smoking. And smokers are known to develop bronchitis. So we should first rule out bronchitis in your case. Consult pulmonologist and get done 1. Clinical examination of respiratory system 2. PUT (Pulmonary Function Test). PFT is must for the diagnosis of bronchitis. It will also tell you about severity of the disease. And treatment of bronchitis is based on severity only. You may need inhaled bronchodilators and inhaled corticosteroid (ICS). Don't worry, you will be alright. Hope I have solved your query. Wish you good health. Thanks.
