My sister has a 3yr9mths old daughter..she fell ill since last thursday, and we couldn't seem to find out what really happened, cos at one time she would feel normal, and then her body temperature rose all suddenly! We tried going to hospitals & clinics but all they did was gave her some medicine, which doesnt work at all. What is really happening to her? We are very worried, as we are absolutely suprised because she has never been like this. We don't think this is a normal illness..HELP!
