Abstract
In clinical medicine, understanding the distinction between a sign and a symptom is essential for accurate diagnosis and effective patient management. A sign refers to an objective, observable indication of a disease detected by a healthcare professional, while a symptom represents a subjective experience reported by the patient. This paper explores the conceptual and practical differences between signs and symptoms, provides examples from various medical contexts, and emphasizes their combined importance in clinical assessment. The study concludes that integrating both elements enhances diagnostic accuracy and improves communication between clinicians and patients.
