My daughter is 27. She has been experiencing headaches, vomiting, diarrhea, cold sweats, loss of appetite, weight loss and a high white blood cell count. She has also diabetes. She has had an endoscopy which showed inflammation of the intestine and esophagus and several negative CT scans. All other blood work is normal and c diff was negative. They say it is a viral infection and there is nothing that they can do. Frustrated. What else should she be tested for?
