My 6 year old daughter has been complaining of stomach ache at night over the last few months. Today she told me that she had to stop running at school because her chest hurts. She tends to get constipated even though she eats exactly what my boys eat. She woke from a nightmare earlier tonight, complaining of feeling too hot and her hair was damp with sweat. Her skin was cold, damp and pale. She had no symptoms leading into bedtime and she says she feels hungry even though she ate plenty at dinner. What should I be looking out for, if anything?
