Continual or Unusual Fever

Usually, fever is caused by your body heating up to ward off an infection like influenza. Persistent or unusual fever, however, could be a sign of a more serious condition. Various autoimmune disorders, such as rheumatoid arthritis, involve an abnormal immune response, which can lead to fever and other symptoms. Persistent fever could also be a sign of a hidden infection that requires treatment. Less often, fever may be an early symptom of leukemia or lymphoma. Talk with your doctor if you experience unusual or persistently high fever.
