My 14 year old daughter is experiencing bone pain in her arms and legs, back pain, fatigue, loss of appetite, weight loss, fainting spells, frequent infections, easy bruising, nose bleeds, weakness, anemia, headaches, is always cold but gets night sweats, vomiting, has abdominal pain after eating all kinds of food, and has become really pale since last January. Should I been concerned about her health and if so what is wrong with her.
