My 15 year old daughter is home from school today with flu symptoms - probably fever ( I don t have a thermometer), aches and pains, sore throat. She slept most of the day, and just told me her leg went numb, which frightened her. She says her hands have been going numb off and on all day. Last week she had a cold, and we thought she was over it. A day or so ago she mentioned that her hands and feet are always cold. Is this just poor circulation, or what?
