Detailed explanation-1: -A symptom is a manifestation of disease apparent to the patient himself, while a sign is a manifestation of disease that the physician perceives. The sign is objective evidence of disease; a symptom, subjective.

Detailed explanation-2: -For example, a rash could be a sign, a symptom, or both: If the patient notices the rash, it is a symptom. If the doctor, nurse, or anyone other than the patient notices the rash, it is a sign. If both the patient and doctor notice the rash, it can be classed as both a sign and a symptom.

Detailed explanation-3: -In general, those symptoms that are explained by the patient are called subjective symptoms and those observed by the physician are called objective symptoms. During the examination of the patient, the physician may also elicit certain objective assessment of the patient and these are called the signs.
