My husband has had a fever between 102-104 for nine days now. He has a severe headache but no other symptoms. We went to the ER twice, and the blood results showed he has an inflamed liver, and low white blood cells but nothing alarming. Tested for mono, meningitis, and had a head and chest CT- all came back with nothing wrong. He has taken vicodin and percocet for the headache, but gets no relief.
