<unk> === A medical<unk> is an objective observable indication of a disease, injury, or abnormal physiological state that may be detected during a physical examination, examining the patient history, or diagnostic procedure. These<unk>  are visible or otherwise detectable such as a rash or bruise. Medical<unk> , along with<unk> , assist in formulating diagnostic hypothesis. Examples of<unk>  include elevated blood pressure, nail clubbing of the fingernails or toenails, staggering gait, and arcus senilis and arcus juvenilis of the eyes. Indications A<unk> is different from an "indication" — the activity of a condition ‘pointing to’ (thus "indicating") a remedy, not the reverse (viz., it is not a remedy ‘pointing to’ a condition) – which is a specific reason for using a particular treatment.<unk>  A<unk> is something felt or experienced, such as pain or dizziness.<unk>  are not mutually exclusive, for example a subjective feeling of fever can be noted as<unk> by using a thermometer that registers a high reading. Cardinal<unk>  Cardinal<unk>  are specific even to the point of being pathognomonic. A cardinal<unk> or cardinal<unk> can also refer to the major<unk> or<unk> of a disease. Abnormal reflexes can indicate problems with the nervous system.<unk>  are also applied to physiological states outside the context of disease, as for example when referring to the<unk>  of pregnancy, or the<unk>  of dehydration. Sometimes a disease may be present without showing any<unk>  or<unk>  when it is known as being asymptomatic. The disorder may be discovered through tests including scans. An infection may be asymptomatic which may still be transmissible.<unk>  vs.<unk> <unk>  are different from experienced<unk> . A<unk> of a disorder is something that may be observed by another or detected during a medical examination or procedure. For example high blood pressure may be noted as a<unk> during an examination for which there have been no reported<unk> . A<unk> is something experienced and reportable by a person such as a headache or fatigue.<unk>  may overlap, such as a bloody nose, which the individual experiences as unusual <unk>  and which others observe <unk> . The CDC lists various diseases by their<unk>  such as for measles which includes a high fever, conjunctivitis, and cough, followed a few days later by the measles rash. Syndrome<unk>  are often non-specific, but some combinations can be suggestive of certain diagnoses, helping to narrow down what may be wrong. A particular set of characteristic<unk>  that may be associated with a disorder is known as a syndrome. In cases where the underlying cause is known the syndrome is named as for example Down syndrome and Noonan syndrome. Other syndromes such as acute coronary syndrome may have a number of possible causes.
