My daughter is 4 years old. She has had a fever, (102-104),headache, fatigue, runny nose, sore throat for ten days now. We have been to the doctor twice. She has had a throat swab done and it is not strep throat. She has been on antibiotics(clarithromycin) for 5 days now with no improvement. I am at a loss as to what to do at this point.
