I would be pleased to answer your question .
It is a normal phenomenon to see that hands and feet remaining cold
as the blood flow as a mechanism is directed to the more central organs of the body . The peripherals like the hand and feet get less blood flowing and this compensatory mechanism results in cold feet and hands.
I would advice her to give her the fever
medicine , give her cold sponges , keep her hydrated and you can even put her under a fan to reduce the body temperature .
make sure that you monitor her temperature and look out for any change in her behaviour , dizziness
. You should take her to the doctor if she gets any of the above .
Thanks and Take care
