See a doctor: You may give Ibuprofen for now and chloraseptic spray. But ultimately she needs to be seen by your doctor to do test that can rule out strep throat infection or influenza.

Support: Give her rest, tylenol (acetaminophen) or ibuprofen, chicken soup, soft foods. Hydrate with gatorade or pediolyte, ginger ale. If not better in 3-4 days, or worsens, check with your doctor to make sure not strep throat, or another bacterial infection that could require antibiotics.
