Thanks for your question on Health Care Magic.
I can understand your concern.
In my opinion, you are mostly having post infectious
bronchitis. It is common after viral upper
respiratory tract infection (cold). Your symptoms like
wheezing,
cough with expectoration, coughing attacks etc are suggestive of bronchitis more.
So better to
consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test).
PFT will not only diagnose bronchitis but 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).
Oral anti inflammatory drugs are also indicated.
So first diagnose yourself and then start appropriate treatment.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
