Thanks for your question on Health Care Magic.
I can understand your concern.
No this is not normal.
You are still having infection.
Fever on antibiotic suggestive of persistent infection. So you need to change the antibiotic.
In my opinion, you should
consult pulmonologist and get done clinical examination of respiratory system,
sputum culture and sensitivity report.
Sputum culture will identify the causative organism. And sensitivity report will guide about appropriate effective antibiotic treatment.
By this we can fasten the recovery and prevent
drug resistance.
Also start inhaled bronchodilators and inhaled corticosteroid (ICS). These will also help in suppression of inflammation and fever.
So consult pulmonologist and discuss all these.
Hope I have solved your query.
Wish you good health. Thanks.
