Thanks for your question on Health Care Magic.
I can understand your concern.
By your history and description, possibility of
bronchitis is more.
Bronchitis is common after viral upper
respiratory tract infection (URTI). And
wheezing, coughing after flu symptoms is suggestive of post infectious bronchitis more.
So better to
consult pulmonologist and get done
1. Clinical examination of respiratory system
2. Chest x ray
3. PFT (Pulmonary Function Test).
Chest x ray is needed to rule out
lung infection.
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.
