I have a question my grandson who is 12 years old. He have symptoms of high fever 102 to 103 for 3 days, low white blood count, dehydration, nausesa, headaches, no energy and no appettite and diziness. One doctor thought he had appendicitis but a cat scan did not show anything. One doctor said he has a infection, but did not give him any antibiotics. What should we do?
