question: Daughter 14 had temp of 102 yesterday, runny nose, coughing, we think flu,  today this AM normal. laying down yesterday to rest, took Tylenol last night, before bed at 6:45 PM, this AM got up walked from one room to another distance maybe 15' stood in front off mirror and felt light headed and fainted, then walked back to bed, is thirsty, has not eaten much , never had any fainting before, we think it is just lack of eating that much since she is not feeling well maybe she is weak.  first time in along time she has ever been sick, she plays soccer, basketball and is always in good health -- do you think we should be concerned
