Symptoms and Signs of Diseases
A symptom is a subjective evidence of disease. A symptom may not be observable by another person. Anxiety, lower back pain, and fatigue are all sensations that only the patient can perceive. In contrast, a sign is objective evidence of disease. Fever, bruises, or rashes are signs that are evident to the patient or another observer such as a doctor.
