16 year old daughter has been home from school sick with fever, mostly low grade, for 3 days, going on 4 days tomorrow. Today, even with Advil 2 hrs earlier, fever is 100.4, Headache for last 2 days and just a general yucky feeling, doesn t want to eat. when she does eat she feels nauseous. Do I need to take her to her dr s? If this is a strand of flu not much they can do. right? It doesn t seem to be the scary high fever flu going around, but what do I know. Please advise. Thank you.
