Sign and Symptom
It is very helpful to evaluate symptoms and signs in diagnosing the causes of
health problems and in monitoring the status of diagnosed diseases. Moreover,
assessment of symptoms and signs is important during treatment with medications
in order to determine the effectiveness of treatment and the development of
side effects.

Symptom: Any subjective evidence of disease. A symptom is a occurrence that
is experienced by an individual. Anxiety, lower back pain, and fatigue are all
symptoms. They are sensations only the patient can perceive. In contrast, a
sign is objective evidence of disease. A bloody nose is a sign. It is evident
to the patient, doctor, nurse, and other observers.
