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.
Alcohol will not help you, so quit alcohol.
Better to
consult pulmonologist and get done clinical examination and PFT (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.
So first diagnose yourself and then start appropriate treatment.
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
