<s>[INST] My daughter has been ill now for approx 2 1/2 wks with various symptoms. Aching legs, very runny nose, lack of appetite, high temp on & off, occasional vomit. Now she seemed to get better about 3 days ago then last night she woke up sweating with a very runny nose and this morning she had a another temp of 39.2! Do you think this is swine flu? She is 3 1/2 and has a brother who s 1 and has pretty much same symptons. Thanks [/INST] Hello, Aching legs and running nose may not be interlinked. Your history quit suggests me of the viral illness, swine flu chances are less.  Since your daughter is having a lack of appetite, it better to visit the hospital and get her clinically examined thoroughly so that you can prevent her from going into deny Chat Doctor.  Hope I have answered your query. Let me know if I can assist you further. Take care  </s>
