Fever

Also known as High body temperature, Warm forehead, Head feeling hot, Increased Body Temperature, Hyperthermia, Pyrexia, Temperature Elevation, Feverish, and Febrile

Fever (also known as pyrexia) is one of the most common medical signs and is characterized by an elevation of body temperature above the normal range of 36.5–37.5 °C (97.7–99.5 °F) due to an increase in the temperature regulatory set-point. This increase in set-point triggers increased muscle tone and chills.
