Main pathways and mechanisms by which pain is transmitted and modulated Biology Diagrams Referred pain is a common but less understood symptom that originates from somatic tissues. Local pain will excite the pathway mediating pain upward to the dorsal horn, while a sensitization process is initiated at the same time. Ochiai N, Kuniyoshi K, et al. Dichotomizing sensory nerve fibers innervating both the lumbar vertebral body The pathway that goes upward carrying sensory information from the body via the spinal cord towards the brain is defined as the ascending pathway, whereas the nerves that goes downward from the brain to the reflex organs via the spinal cord is known as the descending pathway. Pain is a vast subject and affects so many regions of an individual
Referred pain, also called reflective pain, [1] is pain perceived at a location other than the site of the painful 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 back rather than in the thorax (chest), the site of the injury. The International Association for the The mechanism of referred pain is unknown for any particular case. Referred pain can be a major source of confusion in the examination of patients complaining primarily of pain. The fact that pain is referred from visceral internal organs to somatic body structures is well known and commonly used by physicians. Purpose of this review: Referred pain is a common but less understood symptom that originates from somatic tissues. A comprehensive recognition of referred pain is important for clinicians when dealing with it. The purpose of this study is to summarize the current understanding of referred pain, including its pathogenesis, characteristics, diagnosis, and treatment.

Referred pain, as defined by Anderson, is "pain felt at a site different from the injured or diseased organ or body part."ยน Radiating pain, however, is not defined by Anderson; radiating pain is more commonly used in connection with pain perceived in somatic nerve and spinal nerve root distributions (i.e. the dermatomes that all physicians learn early in their training).
Definition/Description [edit | edit source]. Referred pain is pain perceived at a location other than the site of the painful stimulus/ origin. It is the result of a network of interconnecting sensory nerves, that supplies many different tissues. When there is an injury at one site in the network it is possible that when the signal is interpreted in the brain signals are experienced in the

An introduction to pain pathways and mechanisms UCLH Introduction Pain is a vital function of the nervous system in providing the body with a warning of potential or actual injury. It is both a sensory and emotional experience, affected by psychological factors such as past experiences, Referred pain is pain experienced at a site Referred pain may be visceral or somatic, with the former describing pain from an organ and the latter describing pain from the deep tissues such as muscles or joints. In the Ruch's 1961 convergent-projection theory, where afferent visceral sensory pain fibers and somatic fibers enter the same spinal dorsal root ganglia segments of the spinal
