'''Referred pain''', also called '''reflective pain''',<ref name="ArendtNeilsen">{{cite journal |vauthors=Arendt-Nielsen L, Svensson P |title=Referred muscle pain: basic and clinical findings |journal=Clin J Pain |volume=17 |issue=1 |pages=11–9 |year=2001 |pmid=11289083 |doi=10.1097/00002508-200103000-00003|s2cid=27091223 |doi-access=free }}</ref> is [[pain]] perceived at a location other than the site of the painful [[Stimulus (physiology)|stimulus]]. An example is the case of [[angina pectoris]] brought on by a [[myocardial infarction]] ([[heart]] attack), where pain is often felt in the left side of [[neck]], left [[shoulder]], and [[human back|back]] rather than in the [[thorax]] (chest), the site of the injury. The [[International Association for the Study of Pain]] has not officially defined the term; hence, several authors have defined it differently. Referred pain has been described since the late 1880s. Despite an increasing amount of literature on the subject, the [[mechanism (biology)|biological mechanism]] of referred pain is unknown, although there are several hypotheses.

'''Radiating pain''' is slightly different from referred pain; for example, the pain related to a [[myocardial infarction]] could either be referred or radiating pain from the chest. Referred pain is when the pain is located away from or adjacent to the organ involved; for instance, when a person has pain only in their [[jaw]] or left [[arm]], but not in the chest. Radiating pain would have an origin, where the patient ''can'' perceive pain, but the pain also spreads ("radiates") out from this origin point to cause the pain to be perceived in a wider area in addition.
