symptom of phenomenon

Symptom: Any subjective evidence of disease. A symptom is a phenomenon 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.
