Thanks for your question on Health Care Magic.
I can understand your concern.
Yes, possibility of post infectious bronchitis
or lower respiratory tract
infection (LRTI) is more in your case.
Both these conditions are common after viral upper respiratory tract infection (URTI).
And both of them cause pleuritic pain (chest pain
on deep breathing).
So better to consult pulmonologist
and get done clinical examination of respiratory system, chest x ray
and PFT (Pulmonary Function Test).
Chest x ray is needed to rule out LRTI. PFT is needed to rule out bronchitis.
You may need antibiotics, inhaled bronchodilators and inhaled corticosteroid.
So better to first diagnose yourself and then start appropriate treatment.
Hope I have solved your query. Wish you good health. Thanks.
