The initial phase, which lasts for 6 weeks, manifests as nociceptive pain that may be followed by neuropathic pain. In 5%–10% of patients with stump pain, the pain evolves to become predominantly neuropathic. In addition, stump pain can be arthrogenic, osteogenic, or infectious. History and physical examination are important in order to determine the origin of pain. Residual persistent ischemia of the stump should be ruled out. The stump should be examined and investigated to rule out the presence of a neuroma. Occasionally, radicular pain, which arises from the lumbosacral levels, presents as stump pain. The most effective management of stump pain is multidisciplinary and multimodal. Acute stump pain is treated with either epidural analgesia or, more commonly, peripheral nerve blocks. Chronic neuropathic pain is treated with antiepileptics such as gabapentin or pregabalin and NMDA receptor antagonists. Transcutaneous electrical nerve stimulation, spinal cord stimulation, and peripheral nerve stimulation play a limited role in management of stump pain. Neuromas are treated with radiofrequency ablation, cryoablation, or coblation. Surgery is the least successful modality to treat neuroma.","PeriodicalId":87440,"journal":{"name":"Journal of neuropathic pain & symptom palliation","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73039714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The condition is often resistant to treatment and patients often have comorbid syndromes or psychological factors.

Peripheral arterial disease affects 5% of men and 2.5% of women and results in ischemic pain and claudication. Disease progression occurs in a small minority of patients to a stage of critical ischemia with rest pain and threatens limb survival. Ischemic neuropathy encompasses pain due to several stages of progression of tissue ischemia. Patients may have multiple comorbid conditions due to the same pathological process that affects coronary, cerebral, and other circulations. Diabetes mellitus is commonly associated with vascular ischemia and results in arterial occlusive diseases. Pathological changes involve demyelination, axonal loss, and disorderly remyelination. In addition to simple palpation of a pulse, Doppler flow estimation and angiography are used to determine the location and extent of the disease process. Ankle-brachial index, toe-brachial index, and digital flow estimations are more sensitive methods used for early identification. In addition to controlling risk factors and the management of comorbid conditions, medication and procedures to restore blood flow play a prominent role in management of ischemic neuropathy. Sympatholysis and spinal cord stimulation are effective methods to help manage chronic pain in advanced cases that are refractory to conventional treatment measures.","PeriodicalId":87440,"journal":{"name":"Journal of neuropathic pain & symptom palliation","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76550977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pharmacotherapy is a key component of a multidisciplinary approach to the management of neuropathic pain and is a treatment limited by analgesic efficacy and dose-related side effects. First-line medications for neuropathic pain include tricyclic antidepressants (TCAs), serotonin-noradrenaline reuptake inhibitors (SNRIs), calcium channel alpha2delta-1 ligands (gabapentin and pregabalin), topical lidocaine (lidocaine patch 5%), and topical capsaicin (capsaicin 8% patch).

There are a variety of malnutrition-based disorders, which can manifest into specific neurological issues. Specifically, vitamins B1, B12, and E and copper deficiencies can all lead to neuropathic disorders that become difficult to treat after prolonged periods of nutritional deprivation.

Peripheral neuropathic pain includes such common pain conditions as painful diabetic neuropathy, postherpetic neuralgia, radiculopathies, post-amputation stump pain, various nerve entrapment syndromes, and neuropathies due to immune, hereditary, metabolic, and toxic factors. Central neuropathic pain is pain caused by stroke, spinal cord injury, spinal infarction, syringomyelia, multiple sclerosis, Parkinson disease, and phantom limb pain. In contrast, some conditions may cause pain through both central and peripheral mechanisms, such spinal stenosis, complex regional pain syndrome type II, Charcot-Marie-Tooth disease, fibromyalgia, and cancer pain.

The pain is located within and associated with sensory dysfunction in a region affected by a prior CVA lesion. The pain is often described as burning, stabbing, and sharp. Allodynia, hyperalgesia, and evoked dysesthesia appear to be major clinical findings for this condition. There are no specific diagnostic criteria for CPSP, and treatment is often difficult.
