My daughter plays basketball and is a freshman in high school. She is very physical in playing sports and is involved with ffa also. She came down with headache, sore throat yesterday but doesn't have it today and very tired. she slept 15 hrs sunday nite to monday morn. she is sleeping 12 hrs so far today. does she maybe have mono, type of flu that's going around or just wearing herself out. she doesn't take vitamins and she hasn't had a fever at all.
