Thanks for your question on Health Care Magic.
I can understand your situation and problem.
Yes, possibility of either
bronchitis or
pneumonia is more in your case.
Both these conditions are caused by infection.
So antibiotics are needed in both of them.
But pneumonia needs higher or combination of antibiotics.
While bronchitis needs inhaled bronchodilators and inhaled corticosteroid (ICS) along with antibiotic.
So better to
consult doctor and get done clinical examination of respiratory system, chest
x ray and PFT (Pulmonary Function Test).
Chest x ray is needed to rule out pneumonia. PFT is needed to rule out bronchitis.
So better to first diagnose yourself and then start appropriate treatment.
No harm in taking antibiotic if indicated.
Hope I have solved your query.
Wish you good health. Thanks.
