Medical Signs and symptoms are signals of injury, illness and disease
One sign or symptom may not be enough to know what’s causing it. A rash in a child could be a sign of any number of things, such as poison ivy, measles, a skin infection, or a food allergy. If the child has the rash along with other signs and symptoms like a high fever, chills, and a sore throat, then a doctor can get a better picture of the illness. A patient’s signs and symptoms don’t give the doctor enough clues to be sure the cause of the illness. Medical tests, like x-rays, blood tests, or a biopsy may be needed.
