My daughter is four years old and for three weeks has been very pale, lethargic and irritable. A week ago she started having a slight temperature at bedtime, she has had this most nights since. She has had loose stools for about a week, she vomited once during the night last Friday, and now for the last few days she has also had a bad cough and is veery hoarse. I m worried that there might be something serious, such as leukemia, wrong with her. I have taken her to our doctor twice who has both times sent us away saying it is something viral . I just don t understand why she has been so out of sorts for so long. She cries very easily and gets tired out quickly. She does play and tries to do normal things but always becomes upset after an hour at the most, and cries inconsolably.
