Without any other symptoms other than high fever? husband is sick. It started Friday and has progressively gotten worse. Today his fever is 103.7. We went to the doctor he thinks its the flu. He has no cough. No congestion. He has fever, dizziness, fatigue. I'm concerned because he had a bad tooth pulled on 12/31. For some reason the dr doesn't believe it could be an infection from that. I just don't know what to do.
