Thanks for your query
Your daughter is having pharyngitis
.It is difficult to say whether its viral or bacterial infection.
Ask her to do the following :
Do warm saline gurgling four times daily for 5 days
Take Vit C 500mg
tablet once daily for a week. Eat plenty of citrous fruits.
Have plenty of fluids.
500mg tablet twice daily for 3 days and thereafter sos
Take Levocetrizine 5mg tablet once daily for 5 days
500mg tablet 1 tab per day for 3 days
Do a throat swab culture sensitivity testing if possible.
But dont self medicate.Get a clinical checkup from your doctor and take his advice.
Hope this helps
Update here how your daughter stays.
Take care :)
