Girls all Happy New Year ? I have a question for you, my daughter is 5 years old, a couple of days ago she had a cough, phlegm, and once her temperature rose slightly, but today I saw white pus in her throat and her eye started to swell. And what kind of treatment should I give her throat? ?? Is it dangerous? I'll go see a doctor tomorrow.
