Main Difference
The main difference between Sign and Symptoms is that the Sign is a semiotic concept; object, quality, event, or entity whose presence or occurrence indicates the probable presence or occurrence of something else; includes words, punctuation, expressions, gestures, notices, road signs, symbols, pictures, etc and Symptoms is a departure from normal function or feeling which is noticed by a patient, reflecting the presence of an unusual state, or of a disease; subjective, observed by the patient, cannot be measured directly
Sign
A sign is an object, quality, event, or entity whose presence or occurrence indicates the probable presence or occurrence of something else. A natural sign bears a causal relation to its object—for instance, thunder is a sign of storm, or medical symptoms signify a disease. A conventional sign signifies by agreement, as a full stop signifies the end of a sentence; similarly the words and expressions of a language, as well as bodily gestures, can be regarded as signs, expressing particular meanings. The physical objects most commonly referred to as signs (notices, road signs, etc., collectively known as signage) generally inform or instruct using written text, symbols, pictures or a combination of these.
The philosophical study of signs and symbols is called semiotics; this includes the study of semiosis, which is the way in which signs (in the semiotic sense) operate.
Symptoms
A symptom (from Greek σύμπτωμα, “accident, misfortune, that which befalls”, from συμπίπτω, “I befall”, from συν- “together, with” and πίπτω, “I fall”) is a departure from normal function or feeling which is noticed by a patient, reflecting the presence of an unusual state, or of a disease. A symptom is subjective, observed by the patient, and cannot be measured directly, whereas a sign is objectively observable by others. For example, paresthesia is a symptom (only the person experiencing it can directly observe their own tingling feeling), whereas erythema is a sign (anyone can confirm that the skin is redder than usual). Symptoms and signs are often nonspecific, but often combinations of them are at least suggestive of certain diagnoses, helping to narrow down what may be wrong. In other cases they are specific even to the point of being pathognomonic.
The term is sometimes also applied to physiological states outside the context of disease, as for example when referring to “symptoms of pregnancy”. Many people use the term sign and symptom interchangeably.
