Signs vs Symptoms
Though signs and symptoms describe the same conditions, these two are different in many characteristics. While signs are what a doctor sees, symptoms are what a patient experiences. 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 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. 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 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.

It is only when the patient experiences certain symptoms that he or she approaches a physician. Symptoms help the physician diagnose the problem. As symptoms are not visible outwards, it is most important that the patient be as descriptive so that the doctor or the physician may be able to assess and evaluate the symptoms.

Symptoms can also be defined as what the patient reports, but which cannot be verified. Feeling tired, feeling dizzy and having pain are some of the symptoms, which cannot be verified. But signs on the other hand can be verified. Signs can be measured in a clinical setting. High or low blood pressure, rapid heart rate or fever, can be measured.

Symptoms are vague but signs are visible. Sign is only an objective indication of some medical fact that may be detected by a physician. These signs may not have any meaning to patients but they are significant for a physician to diagnosis the medical conditions.

One can describe symptom as one that is experienced and reported by a patient. Meanwhile the doctor discovers signs of a disease during a patient’s examination.
