symptom (sim(p)'tom) [Gr. symptoma, occurrence]
Any change in the body or its functions as perceived by the patient. A symptom represents the subjective experience of disease. Symptoms are described by patients in their complaint or history of the present illness. By contrast, signs are the objective findings observed by health care providers during the examination of patients.
Aspects of general symptom analysis include the following: onset: date, manner (gradual or sudden), and precipitating factors; characteristics: character, location, radiation, severity, timing, aggravating or relieving factors, and associated symptoms; course since onset: incidence, progress, and effects of therapy.
