Thanks for your question on Health Care Magic.
I can understand your situation and problem.
By your history and description, possibility of
bronchitis is more.
Bronchitis is common in smokers.
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
lung infection.
PFT is needed to rule out 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).
So
consult doctor and discuss all these.
Hope I have solved your query.
I will be happy to help you further.
Wish you good health. Thanks.
