Expert Answer:

A symptom can be defined as one of the characters of a disease. Meanwhile, sign is the definite indication of a specific disease. While signs are what a doctor sees, symptoms are what a patient experiences.  A high temperature, a rapid pulse, low blood pressure, open wound and bruising can be called as signs. Chills, shivering, fever, nausea, shaking and vertigo are the symptoms.

While signs are the physical manifestation of injury, illness or disease, symptoms can be described as what a patient experiences about the injury, illness or disease. When the patient notices symptoms, it is the others, especially the physician or doctor who notices signs.

While signs are objective, symptoms on the other hand are subjective. Signs are called objective in the sense that they can be felt, heard or seen. Bleeding, bruising, swelling and fever are signs. Symptoms are subjective in the sense that they are not outwardly visible to others. It is only the patient who perceives and experiences the symptoms.
