“Rarely is a fever anything other than an indication that you are ill,” Stanton explains. It’s actually a healthy sign that your body is responding to an infection. The concern then is not with the fever itself, but with what infection is causing the fever. Don’t hesitate to treat it with over-the-counter medicines such as ibuprofen.
Head to the ER if… a fever is accompanied by extreme lethargy or there are other symptoms of infection present. Most concerning to Stanton are “fevers in kids with lethargy, fevers in adults with altered mental status, and fevers with headache and neck pain.”
