Thank you for your query on Healthcare Magic.
Your child seems to have a viral illness with upper respiratory tract
of 2 weks duration requires evaluation.
Monitor temperature with a thermometer and make a chart.
Continue prescribed medication for cold and cough.
If there is fever you can give Tylenol
in prescribed dosage.
Consult your Pediatrician
to look for the focus of any infection and to give specific treatment.
Hope I have answered your query.
