Abstract
Pain affects every living creature at some point in their lives, but we actually know very little about the systems involved in pain. The subjective nature of pain and a dearth of effective tests add extra challenges to the study of pain. Harmful stimulus drives complex mechanisms into action during the pain response. Many chemicals and hormones are affected by this response and, in turn, affect organ systems and bodily function. Prolonged episodes of stress and unresolved pain can lead to a host of medical and behavioral issues when the body’s systems cannot restart or the hormones necessary for survival run wild in the body. Some of these chemicals and hormones may offer potential treatments and cures for pain, however – with enough

Even doctors and scientists work with only a rudimentary knowledge of how and why pain occurs. The complexity and the personal nature of pain make research and advancement a challenging problem. Most modern tests cannot fully account for pain – scans and laboratory tests cannot document the severity of pain, but many tests can reveal pain-related chemicals in the body and potential physical or disease causes. After ruling out potential physical causes, doctors must rely on the patient’s own description of the pain in order to properly treat or manage the …show more content…
The nerve fibers in the foot form part of a nociceptor, a special receptor found all over the body, and start the pain process. The receptors translate the stimulus into an electrical impulse and send the impulse up the leg and towards the spine. A cluster of specialized cells in the spinal cord forms the dorsal horn, which processes the impulse into the spinal cord. The dorsal horn then sends the signal on to the brain, but the horn may also inhibit or amplify the impulse before sending it onward. After the dorsal horn, the signal travels through the neurons of the spinal cord, into the brain, and to the thalamus. The thalamus relays the signal to the somatosensory cortex, the frontal cortex, the limbic system, and other regions of the brain. The somatosensory cortex senses the pain to localize the affected area. The frontal cortex “thinks” about the signal to determine how best to escape and avoid the pain. The limbic system reacts to the pain on an emotional level, determining how unpleasant or tolerable the pain feels. Pain to the head and face take a shortcut through the brain stem to the thalamus (“The trouble with treating pain,”
A. Chronic pain signifies a developing public health issue of huge magnitudes, mainly in view of aging populations in developed countries (Russo).
The most common and well described pain transmission is “gate control theory of pain”. This theory was first proposed by Melzack and Wall in 1965 whereby they used the analogy of gate to explain the inhibition of pain which exists within the dorsal horn of the spinal cord. For instance, when tissue damage occurs, substances such as prostaglandin, serotonin, histamine and bradykinin are released from the injured cell. Individual usually consume or apply pain medications such as NSAIDs whereby these medications will cause electrical nerve impulse at the end of the sensory nerve fiber via nociceptor. Nociceptor is a pain receptor that is commonly found in the skin, cornea of eye and organ of motion such as muscles and ligaments. These nerve impulses
What exactly is pain? According to Webster's dictionary, pain is "physical suffering typically from injury or illness; a distressing sensation in a part of the body; severe mental or emotional distress". Most everyone reading this paper has experienced some form of physical pain at some point during their lives; most everyone has even experienced the common daily pains such as stubbing our toe as we walk through the living room, accidentally biting our tongue as we chew, and having the afternoon headache after a long day of work. No matter the fact that it is unpleasant, pain has a very important role in telling the body that something is not right and leading to behavior that will remove the body from a source of potential injury. Imagine if we could not experience pain. We would not be able to change our behavior in any way when touching the burning hot dish in the oven, resulting in potentially serious burns. We could not recognize that perhaps we twisted an ankle when walking down the stairs, thus continued walking on that foot would exacerbate the injury to the point of not being able to walk at all. Indeed, pain is not pleasant, but in many cases it is an important way for our nervous system to learn from and react to the environment.

Pain is something most people want to get rid of. It would be shocking if a person would want pain or create their own pain. Sounds outrageous, right? The millions of Americans suffering with diseases and conditions, from chronic pain to cancer, all want their pain to simply disappear. But, most people are aware that some treatment options and pharmaceuticals don’t always work. As a result, they are forced to live with their conditions or diseases for long amounts of time, sometimes even leading to their death. Other times, treatment options and pharmaceuticals that don’t medically have any pain-relieving or curing effect do work. In turn, patients who suffered with cancer or post-tooth extraction pain are relieved with nothing but a
Dendrites are located on either one or both ends of a cell.The peripheral nervous system then takes the sensory information from the outside and sends the messages by virtue of neurotransmitters. Neurotransmitters are chemicals that relay signals through the neural pathways of the spinal cord. The neurotransmitter chemicals are held by tiny membranous sacs located in the synaptic terminals. Synaptic terminals are located at the ends of nerve cells. The release of neurotransmitters from their sacs is stimulated once the electrical nerve impulse has finished travelling along a neuron and reaches the synaptic terminal. Afterward, neurotransmitters travel across synapses thus stimulating the production of an electrical charge that carries the nerve impulse onward. Synapses are junctions between neighboring neurons. This procedure is reiterated until either muscle movement occurs or the brain picks up on a sensory reaction. During this process, messages are being transmitted from one part of the body onto the next. The peripheral and central nervous system are two crucial subdivisions of the nervous system. The brain and spinal cord make up the central nervous
The gate control theory of pain states that non-painful input closes the "gates" to painful input, which prevents pain sensation from traveling to the central nervous system. Stimulation by non-noxious input is able to suppress pain (Melzack). The gate control theory of pain asserts that non-painful input closes the "gates" to painful input, which prevents pain sensation from traveling to the central nervous system. The human brain is the key component in the sensation of pain.
Conclusions. An adequate and clear understanding of the concept of pain and implementing interventions of pain treatment and management is essential in the clinical settings. Understanding the concept of pain is necessary for its relationships with other concepts that are related and similar to the pain experience for theory building. The in the end, understanding the concept of pain will ultimately benefit the patient and lead to better and approp...
Pain is universal and personal to those who are experiencing it. It is subjectively measured on a scale of 0-10 with zero being no pain and 10 being the worst pain ever. This can be problematic for patients and doctors because this score can be understated or overstated. Doctors will make quick decisions based on this score. Patients might feel not believed because only they can feel the pain. However, untreated pain symptoms may be associated with impaired activities of daily life and decreased quality of life. Pain is defined in our textbook, “as an unpleasant sensory and emotional experience associated with actual or potential tissue damage” (Ignatavicius & Workman, 2016, p 25). Actual pain is understood by most because there is an
Pain, which is defined in its widest sense as an emotion which is the opposite of pleasure (White, 2004, p.455), is one of the major symptoms of cancer, affecting a majority of sufferers at some point during their condition (De Conno & Caraceni, 1996, p.8). The World Health Organization (WHO, 2009, online) suggests that relief from pain may be achieved in more than 90 percent of patients; however, Fitzgibbon and Loeser (2010, p.190) stress that pain may often be undertreated, even in the UK. Foley and Abernathy (2008, p.2759) identify numerous barriers to effective pain management, among which are professional barriers such as inadequate knowledge of pain mechanisms, assessment and management strategies.
Overall, there is an immense amount of research dedicated to understanding the psychobiological causes of phantom pain. A prevalent commonality between the literatures reviewed, suggested that symptoms of phantom pain are a neuro-psychobiological experience rather than a psychological disorder. This was evident by peripheral and central factors that associate the cause of phantom pain with the disruption of sensory nerve impulses due to the damage of sensory nerve fibers after amputation. As well as studies that demonstrated a positive correlation between progressive neuroplastic changes in the cortical reorganisation of the topographical structure in somatosensory cortex and worsening phantom limb pain, inferring that cortical reorganisation mediates the extent of pain experienced.

"There is much pain that is quite noiseless; and that make human agonies are often a mere whisper in the of hurrying existence. There are glances of hatred that stab and raise no cry of murder; robberies that leave man of woman for ever beggared of peace and joy, yet kept secret by the sufferer-committed to no sound except that of low moans in the night, seen in no writing except that made on the face by the slow months of suppressed anguish and early morning tears. Many an inherited sorrow that has marred a life has been breathed into no human ear." George Eliot (1819-80), English novelist,editor. Felis Holt, the Radical, Introduction (1866).What is pain? In the American Heritage Dictionary, pain is referred to as "an unpleasant sensation occurring in varying degrees of severity as a consequence of injury, disease, or emotional disorder." The word is rooted in Middle English, from an Old French piene, from Latin poena, meaning "penalty or pain", and from Greek pointe, meaning "penalty." Pain is a very realistic problem that many individuals face daily.
