so here's the deal, my 6 year old sister is really sick. she has a fever of 39 degrees celcius (102 farenheit), she complains that her knees hurt, she vomits during the night, and i dono what else.
do you think its something serious? this has been happening for about 3-4 days, and she went to the doctor yesterday, and shes going back tomorow. for you health-geeks, is it just the flu and it will pass, or should we be worried because it is more serious? i think she got it from sitting in our pool for too long on a semi-warm day
