Causes of radicular pain are diverse and may include mechanical causes such as herniated intervertebral discs and lumbar foraminal stenosis or systemic causes such as diabetic neuropathy and lupus. A thorough history and meticulous examination are necessary to delineate the involved nerve root and to rule out other conditions. Imaging modalities must be judiciously used to determine the site of compression. Management may start with noninvasive management measures, including physical therapy and medications. It should be guided by patient response, progression of symptoms, and the natural progression of disease.","PeriodicalId":87440,"journal":{"name":"Journal of neuropathic pain & symptom palliation","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72550344","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}

Central neuropathic pain is the most common form of pain in patients with MS, with an estimated prevalence of about 50%. Along with the classical neuropathic pain features, such as spontaneous pain (dysesthesia and burning) and evoked pain (allodynia and hyperalgesia), patients with MS may also suffer from intermittent neuropathic pain, such as trigeminal neuralgia, Lhermitte sign, and glossopharyngeal neuralgia.

The underlying mechanism for the development of SCI pain includes neuronal hyperexcitability, reduced inhibition, neuronal reorganization, and plasticity.

It is highly prevalent, afflicting 7–18% of the general population. Its incidences are much higher, ranging from 20% to 77%, in patients with spine disorder, hip and knee osteoarthritis, or cancer. Neuropathic pain can be severely disabling, with significant personal, societal, and economic cost. Patients with neuropathic pain disorders have significantly reduced health-related quality of life and their treatment costs three times that for matched control subjects. There are enormous challenges in understanding and managing neuropathic pain given the diversity of causes, pathology, mechanisms, and clinical presentations of neuropathic pain conditions. Along with these challenges are opportunities for advancing the mechanistic understanding of neuropathic pain and developing promising therapeutic modalities that include new pharmacological agents, emerging stem cell therapy, and novel neuromodulation paradigms.","PeriodicalId":87440,"journal":{"name":"Journal of neuropathic pain & symptom palliation","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87338604","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 chapter reviews the different psychotherapy approaches to treating neuropathic pain: cognitive-behavioral therapy (CBT), operant-behavioral therapy, mindfulness-based stress reduction (MBSR), and acceptance and commitment therapy (ACT). It is important to note that many of the therapies discussed are intended to be incorporated with other pharmacological or interventional approaches to provide a multimodal level of care and increase chances of outcome success.

The hallmark is brief episodes of intense, radiating pain within the territory of trigeminal nerve distribution. It is typically unilateral, often accompanied by facial spasms and can be triggered by facial movements in a majority of patients. Microvascular compression of trigeminal ganglion is the etiology for most patients with classical trigeminal neuralgia. Some patients can have continuous facial pain in addition to paroxysms of pain. Trigeminal neuralgia is a clinical diagnosis, but MRI is done to rule out secondary causes or to detect microvascular compression. Pharmacological therapy with first-line agents—carbamazepine or oxcarbazepine—is the preferred treatment. Patients with failed pharmacological therapy are considered for surgical decompression, ablation procedures, or Gamma Knife surgery.","PeriodicalId":87440,"journal":{"name":"Journal of neuropathic pain & symptom palliation","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74017483","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}

Radiculopathy typically originates from mechanical nerve root compression due to degenerative spine changes such as disc herniation, spondylosis, or osteoporosis and its associated vertebral compression fractures. The presentation of radicular pain in the thoracic region is more common in the upper thoracic and, with lateral disk herniations, often associated with some amount of axial pain. Clinical symptoms are leg weakness, numbness and tingling across the chest or abdomen or shoulders, spasticity, and bowel or bladder dysfunction. The vast majority of patients with thoracic pain return to their previous functional level without surgical intervention. Strengthening, postural optimization, and general exercise and mobility comprise the cornerstone of all treatment and prevention of thoracic radicular pain. Medication may include a variety of choices, ranging from NSAIDs to anticonvulsants. Medications to address specific health issues leading to thoracic radiculopathy (diabetes mellitus and osteoporosis) may be of additional benefit. Thoracic epidural injections or paravertebral blocks with corticosteroids and local anesthetics may be a treatment consideration. Surgical intervention is reserved for patients in whom conservative management has failed and who have persistent pain symptoms. Myelopathy is an indication for surgical intervention. Spinal cord stimulation may be effective to address chronic radiculopathy in selected patients.","PeriodicalId":87440,"journal":{"name":"Journal of neuropathic pain & symptom palliation","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85899015","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}

GPN is characterized by unilateral paroxysmal pain in the oropharynx, nasopharynx, larynx, base of the tongue, tonsillar region, and lower jaw, as well as the ipsilateral ear. There are several causes, including tumors, elongated styloid process (Eagle’s syndrome), and vascular compression; however, most cases are considered idiopathic. Treatment for GPN includes treatment of the secondary causes, while medical treatment is similar to that for trigeminal neuralgia. Techniques for cervical, extraoral, intraoral, fluoroscopic, or ultrasound-assisted glossopharyngeal nerve block have been described, and neurolytic techniques such as cryoneuroablation and radiofrequency denervation are available.
