A symptom is an indication of disease, illness, injury, or that something is wrong in the body. Symptoms are felt or noticed by a person, but can not be easily observed by anyone else. For example, chills, weakness, malaise, shortness of breath and cough may be symptoms of pneumonia. A sign is a sign that something is wrong in the body. But signs are defined as things that can be seen by a doctor, nurse or health care professional. Fever, rapid breathing and abnormal breathing sounds heard through a stethoscope may be signs of pneumonia.
Having one symptom or sign may not give enough information to suggest a cause. For example, a rash in a child can be a symptom of a number of things such as poison ivy, an infectious disease like measles, an infection limited to the skin or an allergy to food. But if the rash is seen along with other signs and symptoms such as high fever, chills, malaise, sore throat, then a doctor can get a better idea of the disease. In many cases, a patient’s signs and symptoms do not give enough clues by themselves for the doctor to determine the cause of a disease. Then medical tests such as x-rays, blood tests or biopsy may be necessary. Read the rest of this entry »
