Thanks for your question on Health Care Magic.
I can understand your situation and problem.
By your history and description, possibility of post infectious
bronchitis is more in your case.
Bronchitis is common after viral infection and you had it 9 months ago.
Your all symptoms like
cough, phlegm and
shortness of breath etc are suggestive of bronchitis only.
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 other lung conditions. PFT is needed 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, first diagnose yourself and then start appropriate treatment.
Hope I have solved your query.
Wish you good health. Thanks.
