Every pain syndrome has an inflammatory profile consisting of the inflammatory mediators that are present in the pain syndrome. The inflammatory profile may have variations from one person to another and may have variations in the same person at different times. The key to treatment of Pain Syndromes is an understanding of their inflammatory profile. Pain syndromes may be treated medically or surgically. The goal should be inhibition or suppression of production of the inflammatory mediators and inhibition, suppression or modulation of neuronal afferent and efferent (motor) transmission. A successful outcome is one that results in less inflammation and thus less pain. We hereby briefly describe the inflammatory profile for several pain syndromes including arthritis, back pain, neck pain, fibromyalgia, interstitial cystitis, migraine, neuropathic pain, complex regional pain syndrome/reflex sympathetic dystrophy (CRPS/RSD), bursitis, shoulder pain and vulvodynia. These profiles are derived from basic science and clinical research performed in the past by numerous investigators and serve as a foundation to be built upon by other researchers and will be updated in the future by new technologies such as magnetic resonance spectroscopy. Our unifying theory or law of pain states: the origin of all pain is inflammation and the inflammatory response. The biochemical mediators of inflammation include cytokines, neuropeptides, growth factors and neurotransmitters. Irrespective of the type of pain whether it is acute or chronic pain, peripheral or central pain, nociceptive or neuropathic pain, the underlying origin is inflammation and the inflammatory response. Activation of pain receptors, transmission and modulation of pain signals, neuro plasticity and central sensitization are all one continuum of inflammation and the inflammatory response. Irrespective of the characteristic of the pain, whether it is sharp, dull, aching, burning, stabbing, numbing or tingling, all pain arise from inflammation and the inflammatory response. We are proposing a re-classification and treatment of pain syndromes based upon their inflammatory profile.

Recent insights have demonstrated a central role for dopaminergic neurotransmission in modulating pain perception and natural analgesia within supraspinal regions, including the basal ganglia, insula, anterior cingulate cortex, thalamus and periaqueductal gray. In addition, while the participation of serotonin and norepinephrine in spinal descending inhibition of pain is well known, a critical role for dopamine in descending inhibition has also been demonstrated. Decreased levels of dopamine likely contribute to the painful symptoms that frequently occur in Parkinson's disease. Moreover, abnormalities in dopaminergic neurotransmission have been objectively demonstrated in painful clinical conditions, including burning mouth syndrome, fibromyalgia and restless legs syndrome. Evidence from animal models and indirect evidence from pharmaceutical trials also suggest a role for dopamine in chronic regional pain syndrome and painful diabetic neuropathy. Several novel classes of medication with analgesic properties have bearing on dopaminergic activity as evident in the capacity of dopamine antagonists to attenuate their analgesic capacity. An expanded appreciation for the role of dopamine in natural analgesia provides the impetus for further study involving preclinical models and advanced neuroimaging techniques in humans, which may lead to the development of novel therapeutic strategies.

The somatosensory system is an integral component of the motor control system that facilitates the recognition of location and experience of peripheral stimuli, as well as body part position and differentiation. In chronic pain, this system may be disrupted by alterations in peripheral and cortical processing. Clinical symptoms that accompany such changes can be difficult for patients to describe and health care practitioners to comprehend. Patients with chronic pain conditions such as complex regional pain syndrome or fibromyalgia typically describe a diverse range of somatosensory changes. This article describes how sensory information processing can become disturbed in fibromyalgia syndrome and complex regional pain syndrome and how symptoms can potentially be explained by the mechanisms that generate them.

Fibromyalgia is a condition characterized by long term body-wide pain and tender points in joints, muscles and soft tissues. Other symptoms include chronic fatigue, morning stiffness, and depression. It is well known that these symptoms are exacerbated under periods of high stress. When pain becomes severe enough, the mind can enter what is known as a dissociative state, characterized by depersonalization - the feeling of detachment from one's physical body and the illusion of watching one's physical body from outside. In evolutionary terms, dissociative states are thought to be an adaptive mechanism to mentally distance oneself from pain, often during trauma. Similar dissociative experiences are reported by subjects who have used psychoactive drugs such as ketamine. We have previously used non-invasive mirror visual feedback to treat subjects with chronic pain from phantom limbs and suggested its use for complex regional pain syndrome: once considered intractable pain. We wondered whether such methods would work to alleviate the chronic pain of fibromyalgia. We tested mirror visual feedback on one fibromyalgia patient. On 15 trials, the patient's lower limb pain rating (on a scale from 1 to 10) decreased significantly. These preliminary results suggest that non-invasive dissociative anesthetics such as VR goggles, ketamine, and mirror visual feedback could be used to alleviate chronic pain from fibromyalgia. This would furnish us with a better understanding of the mechanism by which external visual feedback interacts with the internal physical manifestation of pain.

Although the pain of fibromyalgia usually is not preceded by an injury to the involved tissue, whereas that of the complex regional pain syndrome usually starts at a site of prior trauma or surgery, both disorders may share a common mechanism-pathologic sensitization of brain mechanisms that integrate nociceptive signals-and both apparently respond to treatment with ketamine, an anesthetic-analgesic agent whose actions include blockade of N-methyl-D-aspartate receptors. Ketamine's widespread illegal use as a recreational agent probably precludes developing it as a general treatment of centrally mediated pain disorders; however, its efficacy suggests that related, to-be-discovered agents could be useful.

Chronic pain can develop from numerous conditions and is one of the most widespread and disabling health problems today. Unfortunately, the pathophysiology of chronic pain in most of these conditions, along with consistently effective treatments, remain elusive. However, recent advances in neuroimaging and neurophysiology are rapidly expanding our understanding of these pain syndromes. It is now clear that substantial functional and structural changes, or plasticity, in the central nervous system (CNS) are associated with many chronic pain syndromes. A group of cortical and subcortical brain regions, often referred to as the "pain matrix," often show abnormalities on functional imaging studies in persons with chronic pain, even with different pain locations and etiologies. Changes in the motor and sensory homunculus also are seen. Some of these CNS changes return to a normal state with resolution of the pain. It is hoped that this knowledge will lead to more effective treatments or even new preventative measures. The purpose of this article is to review recent advances in the understanding of the CNS changes associated with chronic pain in a number of clinical entities encountered in the field of physical medicine and rehabilitation. These clinical entities include nonspecific low back pain, fibromyalgia, complex regional pain syndrome, postamputation phantom pain, and chronic pain after spinal cord injury.

Reflex Sympathetic Dystrophy is rare in pediatrics. It is a complex regional pain syndrome, of unknown etiology, usually post-traumatic, characterized by dysfunctions of the musculoskeletal, vascular and skin systems: severe persistent pain of a limb, sensory and vascular alterations, associated disability and psychosocial dysfunction. The diagnosis is based in high clinical suspection. In children and adolescents there are aspects that are different from the adult ones. Excessive tests may result in worsening of the clinical symptoms. Bone scintigraphy can help. Pain treatment is difficult, not specific. Physical therapies and relaxation technics give some relief. Depression must be treated. This syndrome includes fibromyalgia and complex regional pain syndrome type I. We present a clinical report of an adolescent girl, referred for pain, cold temperature, pallor and functional disability of an inferior limb, all signals disclosed by a minor trauma. She had been diagnosed depression the year before. The bone scintigraphy was a decisive test. The treatment with gabapentin, C vitamin, physiotherapy and pshycotherapy has been effective.

Myofascial pain syndrome (MPS) has been defined as a regional pain syndrome characterized by muscle pain caused by myofascial trigger points (MTrPs) clinically. MTrP is defined as the hyperirritable spot in a palpable taut band of skeletal muscle fibers. Appropriate treatment to MTrPs can effectively relieve the clinical pain of MPS. Needling therapies, such as MTrP injection, dry needling, or acupuncture (AcP) can effectively eliminate pain immediately. AcP is probably the first reported technique in treating MPS patients with dry needling based on the Traditional Chinese Medicine (TCM) theory. The possible mechanism of AcP analgesia were studied and published in recent decades. The analgesic effect of AcP is hypothesized to be related to immune, hormonal, and nervous systems. Compared to slow-acting hormonal system, nervous system acts in a faster manner. Given these complexities, AcP analgesia cannot be explained by any single mechanism. There are several principles for selection of acupoints based on the TCM principles: "Ah-Shi" point, proximal or remote acupoints on the meridian, and extra-meridian acupoints. Correlations between acupoints and MTrPs are discussed. Some clinical and animal studies of remote AcP for MTrPs and the possible mechanisms of remote effectiveness are reviewed and discussed.

Transcranial magnetic stimulation (TMS) is a non-invasive method for activating specific areas of the brain. There are two variants, repetitive TMS (rTMS) and direct TMS. Rapid changes in an electrical current induce a magnetic field, which in turn induces an electrical current in a nearby conductor. When a coil is positioned over the brain, rTMS delivers very brief and painless magnetic pulses to the brain. Initially, rTMS was developed as a treatment for depression. Since then, potential indications have been extended to the treatment of chronic pain, most notably in patients with rheumatic diseases. Thus, active research is being conducted into rTMS effects in fibromyalgia, chronic low back pain, and type I complex regional pain syndrome. Studies have established that rTMS is safe; provides pain relief, at least in the short-term; and improves the psychological correlates of chronic pain. These data support further development efforts with the goal of using rTMS in patients with chronic pain, including those with rheumatic diseases. French physicians have shown a high level of interest in rTMS, and the first French recommendations for using this method were issued in 2011. Further research is needed to determine the optimal stimulation parameters, session frequency, and session duration, as well as the best indications. Physicians who see many patients with chronic pain, such as rheumatologists, should be aware of this developing non-pharmacological and safe treatment modality, which can be of considerable help to their patients.

One of the objectives of the Professional Practice Committee (PPC) of the Physical and Rehabilitation Medicine (PRM) Section of the Union of European Medical Specialists (UEMS) is the development of the field of competence of PRM physicians in Europe. To achieve this objective, UEMS PRM Section PPC has adopted a systematic action plan of preparing a series of papers describing the role of PRM physicians in a number of disabling health conditions, based on the evidence of effectiveness of PRM interventions. Generalised and regional soft tissue pain syndromes constitute a major problem leading to loss of function and disability, resulting in enormous societal burden. The aim of this paper is to describe the unique role of PRM physicians in the management of these disabling conditions that require not only pharmacological interventions but also a holistic approach including the consideration of body functions, activities and participation as well as contextual factors as described in the ICF. Evidence-based effective PRM interventions include exercise and multicomponent treatment including a psychotherapeutic intervention such as cognitive behavioural therapy (CBT) in addition to exercise, the latter based on strong evidence for reducing pain and improving quality of life in fibromyalgia syndrome (FMS). Balneotherapy, meditative movement therapies, and acupuncture have also been shown as efficacious in improving symptoms in FMS. Emerging evidence suggests the use of transcranial magnetic or direct current stimulation (rTMS or tDCS) in FMS patients with intractable pain not alleviated by other interventions. Graded exercise therapy and CBT are evidence-based options for chronic fatigue syndrome. The use of some physical modalities and manipulation for myofascial pain syndrome is also supported by evidence. As for complex regional pain syndrome (CRPS), strong evidence exists for rTMS and graded motor imagery as well as moderate evidence for mirror therapy. Interventional techniques such as blocks and spinal cord stimulation may also be considered for CRPS based on varying levels of evidence. PRM physicians' functioning oriented approaches on the assessment and management, adopting the ICF as a reference, may well meet the needs of patients with soft tissue pain syndromes, the common problems for whom are loss of function and impaired quality of life. Available evidence for the effectiveness of PRM interventions serves as the basis for the explicit role of PRM specialists in the management of these health conditions.
