Thank you for waiting.
I am very sorry for your symptoms.
I understand your concern.
Antibiotic can take some time to act.
It can take 2-3 days too to have its full effect.
When you are taking it for so long, I feel you need a review by doctor.
The antibiotic may not be working or there can be a complication.
A few tests or blood work would be needed.
You can take paracetamol meanwhile.
You can keep the room warm & humidified.
It would ease breathing.
I hope this information will be helpful.
If you have any query, please feel free to ask.
Your satisfaction is my goal.
