Hello! I just picked my daughter, who is 8, up from school, because of complaint of a headache, sore throat, and now a canker sore. She is also complaining of a stomach ache. I had asked when the last time she had a bowel movement and she doesn t remember. My daughter has been having this headache and sore throat with stomach now every s six months and the last time our doctor put her on a steroid, because they couldn t find what was wrong with her. I keep looking online for answers and even a medical book. I keep getting either influenza or a psychological disorder.
