Signs and symptoms are diagnostic indications of an illness, injury, or condition.

Signs are objective and externally observable; symptoms are a person's reported subjective experiences.[1]

A sign for example may be a higher or lower temperature than normal, raised or lowered blood pressure or an abnormality showing on a medical scan. A symptom is something out of the ordinary that is experienced by an individual such as feeling feverish, a headache or other pains in the body.[2][3]
