What's the difference between a sign and a symptom?
A sign is the physical manifestation of an illness, injury or other bodily disoreder.
A sign is objective and can be observed by others, where as a symptom is subjective and may be only known to the patient experiencing it.
Signs can be felt, heard, seen, measured by the diagnostician or nurse. These include pulse, respirations, blood pressure, and physical evidence such as bleeding, broken skin, bruising etc.
