Contribute to the reduction of <b>GABAergic\/glycinergic inhibition<\/b>, the imbalance of the <b>top-down control<\/b> (decreased inhibition and increased facilitation from the brainstem), and processes of <b>neuroinflammation<\/b> with activation of <b>microglia<\/b> and astrocytes that release pronociceptive mediators. Functional changes in cortical pain networks that modulate sensory gain and processing of nociceptive signals have also been described.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Sintomas_y_manifestaciones_frecuentes_de_la_sensibilizacion_central_en_personas_con_dolor_persistente\"><\/span>Common symptoms and manifestations of central sensitisation in persons with persistent pain<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Central sensitisation is associated with a <b>amplification of nociceptive signals<\/b> in the nervous system. In people with persistent pain, this can result in a pain response disproportionate to the stimulus, pain spread to uninjured areas, and daily fluctuations with no clear single trigger.<\/p>\n<ul>\n<li><b>Hyperalgesia<\/b>pain: increased intensity of pain in response to stimuli that would normally be painful.<\/li>\n<li><b>Alodynia<\/b>pain: pain to non-painful stimuli, such as rubbing of clothing or light pressure.<\/li>\n<li><b>Generalised or migratory pain<\/b>distribution: wide, shifting and often bilateral distribution, not limited to a specific nerve territory.<\/li>\n<li><b>Sensory hypersensitivity<\/b>discomfort or worsening of pain with intense light, noise, odour, temperature or vibration.<\/li>\n<li><b>Temporary submersion and residual pain<\/b>pain: progressive increase in pain with repeated stimuli and persistence of pain after cessation of the stimulus.<\/li>\n<li><b>Paresthesias and dysesthesias<\/b>tingling, burning or \u201cburning\u201d sensation with no obvious peripheral cause.<\/li>\n<li><b>Sleep disturbances<\/b>sleep and frequent awakenings, which are often associated with increased sensitivity the next day.<\/li>\n<li><b>Fatigue and cognitive fog<\/b>marked tiredness, mental sluggishness and difficulty in concentrating or remembering recent information.<\/li>\n<\/ul>\n<p>These manifestations can be intensified by <b>stress<\/b>, The pain intensity is often not clearly related to peripheral findings. Pain intensity is often not clearly related to peripheral findings. Coexistence of functional symptoms such as tension or migraine headache, temporomandibular pain, pelvic or abdominal discomfort and urinary urgency is common, without implying a single causal mechanism. The presence and combination of these symptoms varies between individuals and, by themselves, do not establish a specific diagnosis.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Como_se_diagnostica_la_sensibilizacion_central_evaluacion_clinica_pruebas_complementarias_y_diagnostico_diferencial\"><\/span>How central sensitisation is diagnosed: clinical assessment, complementary tests and differential diagnosis<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Evaluacion_clinica\"><\/span>Clinical assessment<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The <b>clinical diagnosis<\/b> part of a <b>guided interview<\/b> and a <b>physical examination<\/b> aimed at identifying an amplified and generalised pain pattern.

Temporal summation of pain (increased pain with repeated stimuli) and diffuse pressure sensitivity support the diagnosis. Validated questionnaires, such as the Central Sensitisation Inventory (CSI), can provide complementary information, but do not in themselves constitute diagnostic confirmation.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Pruebas_complementarias\"><\/span>Complementary tests<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>There is no <b>complementary test<\/b> or specific biomarker. Tests are used to rule out alternative causes and, when available, to detect alterations in pain processing: quantitative sensory assessment (thermal and pressure thresholds), measurement of temporal summation and conditioned pain modulation, or algometry. Basic blood tests and imaging studies are requested according to clinical signs to exclude inflammatory, autoimmune, endocrine or structural pathology.

The presence of triggers, comorbidities (e.g. headache, mood disorders, irritable bowel syndrome) and psychosocial factors that may modulate the painful experience are assessed. Physical examination is aimed at differentiating active nociceptive\/neuropathic generators, ruling out \u201cred flags\u201d and estimating movement and load tolerance. Realistic functional goals are proposed and a <b>multimodal approach<\/b> with shared decision-making and regular monitoring.<\/p>\n<p>Combined and progressive non-pharmacological interventions are at the core of management. The <b>pain education<\/b> helps to reinterpret symptoms and align expectations. The <b>graduated exercise<\/b> (low to moderate intensity aerobic, strength and mobility with progressive exposure) aims to improve capacity without exacerbating flare-ups; pacing and self-regulation of effort are key. The <b>psychological therapy<\/b> with validated approaches (e.g. cognitive-behavioural or acceptance and commitment) can support coping, reduction of catastrophising and stress management. Routines are recommended for <b>sleep hygiene<\/b>, The programme also includes relaxation and breathing techniques, and adjustments to habits that minimise the physiological burden.<\/p>\n<p>The <b>prudent pharmacotherapy<\/b> is considered when symptoms persist despite non-pharmacological measures or to treat relevant comorbidities. In selected cases, low-dose tricyclic antidepressants, serotonin-norepinephrine reuptake inhibitors or gabapentinoids may be considered after an individual assessment of benefit-risk balance, interactions and preferences; it is suggested to start with low doses, reassess efficacy and adverse effects and deprescribe if they are of no clinical value. Prolonged use of opioids is usually avoided due to their risk profile, and invasive interventions are not considered first-line. Regular monitoring with functional metrics, flare recording and stepwise adjustments supports safety and consistency of the treatment plan.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Trastornos_en_los_que_puede_estar_presente_la_sensibilizacion_central_fibromialgia_migrana_sindrome_de_intestino_irritable_y_otros_cuadros\"><\/span>Disorders in which central sensitisation may be present: fibromyalgia, migraine, irritable bowel syndrome and other conditions.<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The <b>central awareness<\/b> describes a state of <b>hyperexcitability of the central nervous system<\/b> with <b>amplified sensory processing<\/b>, which can manifest itself as <b>hyperalgesia<\/b> (increased pain), <b>allodynia<\/b> (pain to non-painful stimuli) and sensitivity to light, noise or temperature.
