what is visceral pain

Their termination in the spinal cord is noteworthy on several counts. In a figurative sense, something "visceral" is felt "deep down." Visceral pain responses are provoked by ischemia, inflammation, and distention. As indicated in the section Visceral Sensory Innervation, visceral pain is not necessarily linked to organ injury, which begs the question: What stimuli are appropriate to generate the sensation of pain from the viscera? The American Journal of Physiology 300: G170–G180. The mechanisms linking visceral pain with these overlapping comorbidities remain to be elucidated. To understand the neurobiology of visceral pain requires use of the dual approach of animal investigation coupled with investigations in humans. Because vagotomy was found to be generally ineffective in relieving visceral pain, whereas spinal nerve transaction or destruction of sympathetic prevertebral ganglia often provided pain relief (at least for a limited period of time), the spinal visceral nerves (sympathetic afferents) were inferred to be the conveyors of nociceptive information from the organs to the spinal cord. Visceral definition is - felt in or as if in the internal organs of the body : deep. Visceral manipulation is as gentle manual therapy where the therapist feels for altered motion within the organs and uses myofascial techniques to release these restrictions, restore natural motility and mobility, and thus return the body to a more natural and pain-free balance. Zhuo-Ying Tao, ... Dong-Yuan Cao, in Epigenetics of Chronic Pain, 2019. The term "visceral pain" usually is restricted to pain that occurs in, or is produced by, changes in the state of intrathoracic, intra-abdominal or intrapelvic organs. sweating, nausea and vomiting) and highly emotional (e.g. TIMOTHY J. NESS MD, PhD, in Cancer Pain, 2006, There are more than 50 different models of visceral pain that have been described, but only a few have been well characterized.9 These include the common pharmaceutical screening model, the writhing test, which consists of the intraperitoneal injection of a chemical irritant (e.g., acetic acid, phenylquinone, or hypertonic saline) followed by counting the number of writhes produced. Visceral pain is pain that results from the activation of nociceptors of the thoracic, pelvic, or abdominal viscera (organs). Examples of visceral pain include: appendicitis, gallstones, chronic chest pain diverticulitis and pelvic pain. Most commonly, the stimuli include distension of hollow organs, presumably activating stretch/tension receptors in the organ wall, inflammatory mediators derived from inflamed organs, mediators derived in association with ischemia of an organ, and mediators derived from immune-competent cells resident in or attracted to an organ. Referred pain from the viscera, according to the generalizations of Head, is characterized, in part, as … Frontiers in Psychiatry. It is a dull pain from within caused by infiltration, expansion, perforation, blockage, stretching, or irritation of internal organs. Visceral pain is diffuse, difficult to locate, and often referred to a … Visceral Osteopathy. Even though it's estimated that 40 percent of the population experiences visceral pain at some time or another, a lot less is known about it than about somatic pain. Experimentally, mechanical distension of hollow organs has been most widely studied in both human and nonhuman animals and is the stimulus about which most is understood. Visceral pain receptors are located on the serosa surface, in the mesentery, within intestinal muscle, and mucosa of hollow organs. These anatomic characteristics of visceral afferent spinal terminations surely contribute to the diffuse nature of visceral pain and difficulty in localizing its source. Visceral hypersensitivity is a term used to describe an increase in pain sensation, which is more than the normal within the internal organs. See more. Common examples include chest pain and functional abdominal pain. J.-H. La, G.F. Gebhart, in Encyclopedia of the Neurological Sciences (Second Edition), 2014. Pelvic pains caused by disorders in bladder or irritable bowel syndrome can be considered as visceral pain. By continuing you agree to the use of cookies. Visceral pain generally affects the body’s inner organs also known as viscera. Activation of the second-order neuron is illustrated here as being conveyed to the brain via the anterolateral ascending pathway; not illustrated is a postsynaptic dorsal column pathway, which also conveys visceral sensory information to the brain. You can’t always feel it or see it. Thus, effective pain management needs to combine analgesic therapies with treatment strategies targeting specific visceral function. Methodologic and ethical concerns have presented significant constraints to use of this model. Because there are fewer nociceptors in the internal organs as compared to those in the skin and muscles, visceral pain is often diffuse and hard to pinpoint. Spinal masqueraders are conditions which present as lower back pain but are actually caused by non-mechanical referred pain from a visceral structure. Mechanosensitive receptive endings that respond to tension/stretch are those considered to be primarily responsible for visceral pain. Visceral Pain Visceral pain may not be a well known term, but it is a very common experience and a leading cause of visits to hospital emergency departments. Secondly, spinal visceral afferents represent less than 10%, and probably closer to 5%, of the total afferent input into the spinal cord from all tissues. Each organ is innervated by two nerves with some overlapping but, importantly, also different functions. 10.1). Pain involving thoracic, abdominal, or pelvic organs is a common cause for physician consultations, including one‐third of chronic pain patients who report that visceral … Up to 25% of the population report visceral pain. Allodynia. Afferent fibers involved in processing visceral pain are unmyelinated C-fibers that enter the spinal cord bilaterally, resulting in dull, poorly localized pain. Figure 1. Visceral and somatic pain show many differences not only in the psychophysics of the sensation, but also in the neurobiological mechanisms that mediate the sensory process. In the past, visceral organs were considered insensitive to pain but now it is clear that the social burden of visceral pain is much greater than somatic pain. However, persistent stress facilitates pain perception and sensitizes pain pathways, leading to a feed-forward cycle promoting chronic visceral pain disorders. There is also some evidence that people with certain psychiatric conditions, such as bipolar disorder, borderline personality disorder, and post-traumatic stress disorder (PTSD), are more prone to symptoms of visceral pain. Visceral pain occurs when pain receptors in the pelvis, abdomen, chest, or intestines are activated. The cause of this pain could be ischemia of the viscus, distension of the hollow viscus, chemical damage to viscus and visceral peritoneum (due to gastric acid and juices) or stretching of viscus or mesentery. Visceral: Referring to the viscera, the internal organs of the body, specifically those within the chest (as the heart or lungs) or abdomen (as the liver, pancreas or intestines). Modified from Feng B and Gebhart GF (2011) Characterization of silent afferents in the pelvic and splanchnic innervations of the mouse colorectum. Visceral leishmaniasis is a tropical systemic infection caused by protozoa of the genus Leishmania (Leishmania donovani in Asia and Africa, Leishmania infantum in the Mediterranean, and Leishmania chagasi in South America). Dual FAAH and MAGL inhibition might play a key role in visceral pain However, analgesics should still be used for patients undergoing procedures that might cause visceral pain. We will focus on stress-induced exacerbation of chronic visceral pain and provide supporting evidence that centrally acting drugs targeting the pain and stress-responsive brain regions may represent a valid target for the development of novel and effective therapeutics. Visceral pain is pain that arises from, in, or around internal organs. The clinical management of visceral pain is still unsatisfactory. G.F. Gebhart, in Encyclopedia of Neuroscience, 2009. Variations have been described in primates, cats, dogs, and guinea pigs, but the model has been predominantly used in rodents. Visceral pain can be described as generalized pain inside the body, which originates from internal organs, and is usually hard to identify. However, both LT and HT stretch-sensitive afferents have the ability to contribute to visceral pain (see Visceral Hypersensitivity). It is now widely appreciated that mechanosensitive endings with HTs for activation to stretch are considered the principal conveyors of acute nociception arising from the viscera. Mucosal receptors respond to stroking of the mucosa (lines beneath the record) but not stretch. Studies have been performed in multiple laboratories in Europe, Asia, and the Americas with consistent findings among sites. There are significant limitations to what models of visceral pain can tell us about the overall phenomenon. This is simply known as slow pain which is contrast to the rapid onset, excruciating pain that starts within seconds of injury in parietal and somatic pain described below (fast pain). Visceral pain is diffuse, difficult to localize and often referred to a distant, usually superficial, structure. In addition, during their longitudinal journey these main branches give off multiple collateral branches into the spinal dorsal horn (superficial laminae and laminae V and X, including contralateral laminae V and X) where, moreover, their number of terminal swellings are greater than found on cutaneous C-fiber terminations within the spinal dorsal horn (which are typically limited to the spinal segment of entry). Visceral pain, defined as pain originating from the internal organs, is a hallmark feature of multiple diseases, including inflammatory bowel disease, pancreatitis, irritable bowel syndrome (IBS), and functional dyspepsia. Figure 3. Sensitization of low threshold (LT) and high threshold (HT) stretch-responsive afferent endings. Overview of Visceral pain as a medical condition including introduction, prevalence, prognosis, profile, symptoms, diagnosis, misdiagnosis, and treatment Unlike neuropathic pain which is typically a stabbing pain, or somatic pain which is usually an aching pain in a specific area of the musculoskeletal system, visceral pain location is more ambiguous. Visceral nociceptors are sensitized by inflammation and disease, but so too are low-threshold, non-nociceptor mechanosensors. Unilateral nerve blocks or neurolysis are often ineffective, which is partly due to the fact that most viscera receive bilateral innervation and are innervated by two sets of nerves. Current evidence suggests that spinal afferents primarily serve the discriminatory function of nociception, encoding location and intensity of visceral pain. CONTINUE SCROLLING OR CLICK HERE FOR RELATED SLIDESHOW Visceral pain describes pain emanating from the internal thoracic, pelvic, or abdominal organs. And it is referred to mid line. Thus, the treatment of visceral pain represents a major unmet medical need. Muscular endings respond to circumferential stretch (0–170 mN, ∼45 mm Hg), but not stroking (10 mg) of the mucosa. What is visceral pain?
