A high fever of 104 is often due to a severe infection and requires close care to bring it down safely. Take proper rest, drink plenty of fluids, keep your body lightly covered, and use lukewarm sponging to help lower your body temperature. Continue taking the fever medicine only as advised, monitor your temperature every few hours, and watch for signs such as weakness, confusion, or shivering. If the fever does not come down, keeps rising, or you feel very unwell, seek medical help urgently for proper treatment.
