Thanks for your response, I'll try answering one by one.

She started to complain sometime in the begining of last week.
I don't know so cause for the soar throat.
She complains that her throat hurts, nothing in particular, also that inside her mouth it's itching.
She IS thirsty.
She prefers drinking cold.
This morning she complained that her head hurts, indicating along the hairline.
She's running a low grade fever between 100 to 102 F.
It does not seem any difference between day and night. The past night she awoke about 1 AM and asked for a sweater cause she's cold, then at 4:30 she awoke again that she's hot (she had 102 fever at that time) and her head hurts she's itching all over.
Her mood did not change much of her usual.

Thanks again.
