My children is 3 years old she is alway tired and she said foot ache and alway his body is hot and angry alway hair is weet whats reason please help?

See doctor: This is not normal . Conditions such as malabsorption of nutrients, anemia, infection, heart disease, thyroid disease , immune defect, etc need be ruled out. She needs prompt medical attention.

Many possibilities: There are too many possibilities to list for these symptoms and your daughter needs to be evaluated by a Dr to determine what is causing her symptoms. A good physical exam with vitals can help determine the cause. She may need blood tests also. Try to bring her to a Dr as soon as possible!
