A sign is an objective manifestation of a medical condition that can be observed or measured by a healthcare provider. For example, a rash, fever, high blood pressure, or an abnormal heart sound can all be signs of an underlying condition.
On the other hand, a symptom is a subjective experience or perception reported by a patient that is indicative of a medical condition. Symptoms cannot be directly observed or measured by others and can vary from person to person. Examples of symptoms include pain, fatigue, dizziness, nausea, or shortness of breath.
In summary, a sign is an objective finding that can be observed or measured by someone else, while a symptom is a subjective experience reported by the individual experiencing it.
