Sign and symptom

Signs and symptoms are ways our bodies show that something might be wrong. Symptoms are what a person feels, like pain, fatigue, or nausea, which aren't visible to others. Signs are things a doctor can observe or measure, such as a rash, fever, or swelling. Symptoms tell the healthcare provider what the patient experiences, while signs provide objective evidence that can help identify the cause of illness. Both are important for diagnosing health issues accurately and deciding on the best treatment.
