Dear Madam, based on the history that you have given, it looks like your daughter has
upper respiratory infection including
sinusitis and possibly a mild lower
chest infection too.
You could try giving her
1)
povidone-iodine 10% or hot salt water gargles (glass of warm to hot water with a teaspoon of salt) at least thrice a day, along with
2) steam inhalation (take half a bucket of hot steaming water, cover her head with a towel) and allow her to take steam inhalation.
3) I also suggest she takes rest for a few days
and drink hot water and eat hot food
and avoid consumption of
cold foods, like ice cream.
If she feels better she should continue the same for 3 to 5 days till she completely feels normal.
In addition, you could start her on a
cough expectorant with/without an antihistaminic for 5 days.
Despite all the medication if she shows no sign of improvement it is likely she would require consultation for following possibilities
1) Severe
respiratory tract infection : she may require throat and chest examination and subsequent treatment like antibiotics, etc
2) Mild variant of asthama
I hope I could answer your question. Wishing your daughter and you good health, take care.
