General query. 16-year old daughter, in good health otherwise, has following symptoms: very achy legs (muscle, not bone ache). sore upper arms (ditto), the (ahem) runs . No sore throat or cough. Sweats like a pig in heat. Feels faint and light-headed, very sleepy. Slight stuffy nose. I don t think flu , because no fever, just sweaty. Plus no nausea. What say you?
