It sounds as though your Daughter needs a VERY detailed work-up from the symptoms you have described. I wouldn't care to venture a guess as to what the problem may be but I do advise that you continue to investigate this until you have an answer. Either a Pediatrician or Internal Medicine Specialist. This may be something rather serious that needs immediate attention. If you have access to Physicians associated with a Univ. or Teaching Hospital / Medical Center that would be a good place to start. Take care and KEEP LOOKING for the answer.
I took her to the doctor and they did blood work. found out yesterday that her
white blood cell count is low. any clues as to what it might be? she also has constant headaches, fatigue, and severe joint pain
