Fever unsustainable

Fever is a common symptom of many illnesses and is typically characterized by a body temperature above normal range. It usually develops gradually, beginning with a feeling of chilliness, followed by shivering and then a rise in body temperature. Depending on the cause and severity, fever can manifest in different ways, ranging from mild to severe. Mild fevers may cause sweating, headache, fatigue, and loss of appetite, whereas severe fevers may cause delirium, seizures, and confusion.
