Chronic primary pain can affect any body system or site and can also be widespread. [9] Conditions within this category are further classified into chronic widespread pain, complex regional pain syndromes, chronic primary headache and orofacial pain, chronic primary visceral pain, and chronic primary musculoskeletal pain.

Pain disorder is chronic pain experienced by a patient in one or more areas, and is thought to be caused by psychological stress. The pain is often so severe that it disables the patient from proper functioning. Duration may be as short as a few days or as long as many years.
Mental disorders can amplify pain signals and make symptoms more severe. [135] In addition, comorbid psychiatric disorders, such as major depressive disorder, can significantly delay the diagnosis of pain disorders. [136] Major depressive disorder and generalized anxiety disorder are the most common comorbidities associated with chronic pain.
No other diagnosable disorder otherwise explains the pain. [35]: 607 In 2016, the provisional criteria of the American College of Rheumatology from 2010 were revised. [9] The new diagnosis required all of the following criteria: "Generalized pain, defined as pain in at least 4 of 5 regions, is present."
The term "psychogenic pain" has begun to fall out of relevance in the scientific community, due to its implication that the pain is entirely psychological in origin and thus not "real". [11] The change in preferred nomenclature can be traced to 1994 when the DSM-IV removed the term in favor of the more holistic "Pain Disorder" section. [4]
Hyperalgesia (/ ˌ h aɪ p ər æ l ˈ dʒ iː z i ə / or /-s i ə /; hyper from Greek ὑπέρ (huper) 'over' + -algesia from Greek ἄλγος (algos) 'pain') is an abnormally increased sensitivity to pain, which may be caused by damage to nociceptors or peripheral nerves and can cause hypersensitivity to stimulus.
Complex regional pain syndrome (CRPS type 1 and type 2), sometimes referred to by the hyponyms reflex sympathetic dystrophy (RSD) or reflex neurovascular dystrophy (RND), is a rare and severe form of neuroinflammatory and dysautonomic disorder causing chronic pain, neurovascular, and neuropathic symptoms.
Most pain resolves once the noxious stimulus is removed and the body has healed, but it may persist despite removal of the stimulus and apparent healing of the body. Sometimes pain arises in the absence of any detectable stimulus, damage or disease. [3] Pain is the most common reason for physician consultation in most developed countries.
