Symptom

A symptom is a subjective indication of a disease or condition, experienced and reported by the patient, not directly observable by others.

Examples include:

* Pain

* Fatigue

* Nausea

* Dizziness

* Shortness of breath

Note: Unlike signs, which are objective findings detected by a healthcare professional (e.g., fever, rash, abnormal reflexes), symptoms rely on the patient's perception and communication.
