Thanks for using Healthcaremagic,
After going through your available details, your cough and illness is there for last 10 days.
If your x ray is normal and you have taken a course of antibiotic which was given empirically.
In your case it could be viral Pneumonia
or Atypical Pneumonia
along with post viral reaction which sometimes causes severe bronchospasm
, it needs to be treated by anti inflammatory drugs like corticosteroids
and bronchodilators should be continued.
It should resolve in few days and if it persists. Then Lung function test and CT scan of chest may be of help.
Wish you good Health.
