Ipulse stimulator massager9/25/2023 ![]() Many of these characteristics of pain have been associated with specific brain systems, although much remains to be learned. Cognitive-evaluative which involves thoughtful planning on what to do to get away from the pain.Affective-motivational aspect which conveys just how unpleasant the experience.Sensory-discriminative aspect which helps us localize where on our body the injury occurs.This pain experience has multiple components that include the: These cortical brain regions process the nociceptive ( pain causing or reacting to pain) information from the body and generate the complex experience of pain. ![]() The thalamus is a relay station that distributes sensory signals to many other brain regions-including the anterior cingulate cortex, somatosensory cortex, insular cortex, and prefrontal cortex. One central place these signals travel to is the thalamus. Pain signals from the head and face directly enter the brainstem where they join the pain pathways that travel from the spinal cord to the brain. These signals are transmitted to a specialized part of the spinal cord called the dorsal horn, where they can be dampened or amplified before being relayed to the brain. The events begin with conversion of the stimulus to an electrical impulse that travels through nerves from the site of injury or disease process to the spinal cord. To sense pain, specialized receptors (called nociceptors) which are found throughout the body, trigger a series of events in response to a noxious (painful) stimulus. Normally, acute pain is a protective response to tissue damage resulting from injury, disease, overuse, or environmental stressors. We may experience pain as a prick, tingle, sting, burn, or ache. It is not known whether these disorders share a common cause. It is thought that there are common mechanisms that put some people at higher risk to develop multiple pain disorders. People with chronic pain often suffer from more than one painful condition. ![]() It can-and often does-cause severe problems. By its nature, chronic pain persists over a long period of time and is resistant to many medical treatments. Chronic pain can be made worse by environmental and psychological factors. It can become chronic.Ĭhronic pain is now believed to be a chronic disease condition in the same manner as diabetes and asthma. The pain is self-limiting, which means it is confined to a given period of time and severity. The cause of acute pain can usually be diagnosed and treated. This type of pain generally comes on suddenly, for example, after trauma or surgery, and may be accompanied by anxiety or emotional distress. Pain can be classified as acute or chronic, and the two kinds differ greatly.Īcute pain, for the most part, results from disease, inflammation, or injury to tissues. As will be discussed later, there can be a wide variability in how a person experiences pain to a given stimulus or injury. The definition means that pain is a subjective experience one that cannot be objectively measured and depends on the person's self-report. ![]() What is pain? It is an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage.
