Thanks for your question on Health Care Magic.
I can understand your concern.
By your history and description, possibility of either lower
respiratory tract infection (LRTI) or
bronchitis is more.
Both are common after viral upper respiratory tract infection.
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 LRTI (
pneumonia).
PFT is must for the diagnosis of bronchitis.
You may need antibiotics, inhaled bronchodilators and inhaled corticosteroid (ICS).
Don't worry, you will be alright.
Better to first diagnose yourself and then start appropriate treatment.
Hope I have solved your query.
Wish you good health. Thanks.
