Follow-up
Most fevers will go away in a few days with the appropriate treatment. Follow up with the physician to be sure the cause of the fever is treated correctly. This may be done in a few days to weeks after the initial visit, depending on the cause.
If symptoms worsen, if the fever continues for more than 3 days despite treatment, or if the fever lasts longer then a week without treatment, see the doctor immediately.
