From what you have mentioned, it looks like your kid has a severe bacterial conjunctivitis
In such kids, not only the eyes but surrounding skin will also be inflammed.
Along with oral antibiotic, you may ask your doctor for antibiotic eye drops- that will give some comfort to her eyes.
Usually any antibiotic will take a minimum of 48 hrs to act.
You may wait for a couple of days.
Hope my answer helps you.
Wish your daughter a speedy recovery.
