Patient perspective on symptoms of Notalgia paresthetica: subpopulation results from the Neuropathic Itch Patient Survey (NIRVE).

Background: Notalgia paresthetica (NP) is a form of neuropathic itch characterized by recurrent itch in the mid back. Much about NP remains unclear, especially the patient experience.Objectives: The Neuropathic Itch Patient Survey (NIRVE) was a global, online survey conducted to better characterize the symptom burden of neuropathic itch from the patient perspective.Patients and methods: This report focuses on the symptom burden of the subpopulation of NIRVE participants with a self-reported diagnosis of NP (N = 91). Respondents reported visiting a median of 2 healthcare providers (HCPs) for their symptoms before receiving an accurate diagnosis of NP.Results: The most common cutaneous symptoms ever experienced were itch/pruritus, sensitive skin, painful or raw skin, numbness, and tingling. The symptoms reported by the most respondents as currently being experienced included itch/pruritus, numbness, painful or raw skin, tingling, and burning or hot sensation. Of patients currently experiencing symptoms, numbness and itch/pruritus were ranked as the most intense, followed by tingling, burning or hot sensation, and then painful or raw skin. Most patients consult multiple healthcare providers (HCPs) before receiving a diagnosis for their condition.Conclusion: Itch is overwhelmingly the most prevalent symptom of the condition, although half of patients also report experiencing sensitive skin, painful or raw skin, numbness, or tingling.

A systematic review of procedural modalities in the treatment of notalgia paresthetica.

BACKGROUND: Notalgia paresthetica (NP) is a rare condition characterized by localized pain and pruritus of the upper back, associated with a distinct area of hyperpigmentation. Given the lack of standardized treatment and the uncertain efficacy of available options, applying procedural methods is of growing interest in treating NP. AIMS: We sought to comprehensively evaluate the role of procedural treatments for NP. METHODS: We systematically searched PubMed/Medline, Ovid Embase, and Web of Science until November 14th, 2023. We also performed a citation search to detect all relevant studies. Original clinical studies published in the English language were included. RESULTS: Out of 243 articles, sixteen studies have reported various procedural modalities, with or without pharmacological components, in treating NP. Pharmacological procedures, including injections of botulinum toxin, lidocaine, and corticosteroids, led to a level of improvement in case reports and case series. However, botulinum toxin did not show acceptable results in a clinical trial. Moreover, non-pharmacological procedures were as follows: physical therapy, exercise therapy, kinesiotherapy, acupuncture and dry needling, electrical muscle stimulation, surgical decompression, and phototherapy. These treatments result in significant symptom control in refractory cases. Physical therapy can be considered a first-line choice or an alternative in refractory cases. CONCLUSION: Procedural modalities are critical in the multidisciplinary approach to NP, especially for patients who are refractory to topical and oral treatments. Procedural modalities include a spectrum of options that can be applied based on the disease's symptoms and severity.

Notalgia Paresthetica Responding Positively to Chiropractic Spinal Manipulation: A Case Report.

Notalgia paresthetica (NP) is a chronic cutaneous neuropathy characterized by localized pruritus and pain, numbness, and/or paresthesia, often linked to degenerative cervicothoracic changes. Treatment options for NP are limited. This case report details a 54-year-old woman with a six-year history of right-sided periscapular pruritus and cervicothoracic discomfort who presented to a chiropractor upon referral with a prior diagnosis of NP. Prior topical treatments yielded minimal relief. Radiographs revealed degenerative spinal changes at C5/6 and C6/7 which correlated with her periscapular symptom distribution. The patient responded positively to chiropractic spinal manipulative therapy (SMT), focusing on the cervicothoracic region, coupled with myofascial release. Symptoms significantly improved after a single SMT session and resolved after a second session, with no pruritus returning over one-month follow-up. While this case highlights the potential benefits of SMT for NP, further research is needed to explore the effectiveness of this treatment.

Successful treatment of notalgia paresthetica with lidocaine 5% medicated plaster: a case report.

Notalgia paresthetica (NP) is a sensory neuropathy characterized by chronic, localized pruritus in a circumscribed area on the upper back. Pruritus, frequently resistant to treatment, may be accompanied by pain, paresthesia, allodynia and alloknesis. There is a paucity of data in the NP literature about the use of lidocaine 5% medicated plaster. This case involves a 75-year-old woman with NP and a history of many unsuccessful local or systemic treatments. The patient was treated with lidocaine 5% medicated plaster, while other therapies were progressively retired. After 11 weeks of therapy, a significant reduction in the intensity of itching was achieved and the itching area was reduced. The patient also reported an associated improvement in her quality-of-life throughout therapy. In conclusion, lidocaine 5% medicated plaster was successful in relieving itching and other symptoms in this case of NP.

Notalgia paresthetica (NP) is a nerve disorder characterized by itching on the upper back. Sometimes the itch is so painful and intense that it can make it difficult to sleep, work and socialize, affecting quality-of-life. There are different treatments for NP and not everyone will have the same response to treatment. In this case, a woman with long-standing NP, after several unsuccessful therapies, were treated with lidocaine 5% medicated plaster, which can be applied to the skin where it hurts. After 11 weeks of therapy, an important reduction in the intensity of itching was achieved and the itching area was reduced. The patient also reported an improvement in her quality-of-life throughout therapy. In conclusion, lidocaine 5% medicated plaster was successful in relieving severe itch in this NP case.

Understanding the patient experience of living with notalgia paresthetica: A qualitative interview study.

Background: Notalgia paresthetica (NP) is a chronic sensory neuropathy that causes intense pruritus, typically affecting the upper portion of the back and lasting for months to years. The impacts of pruritus and the full symptom experience are not well documented. Objective: To describe patients' NP symptom experience and the impacts of living with NP-related itch. Methods: Semistructured, one-to-one qualitative telephone interviews were conducted in adults living with NP. The worst itch severity during the previous 24 hours was assessed using an 11-point numerical rating scale. Results: Thirty participants (23 females; aged 41-80 years) completed interviews. Seventeen NP-related symptoms were described, with daily itch being the most common. Participants' itch ranged from severe to very severe (50%) and was experienced for a median of 2.8 years. Most (73%) participants were not receiving treatment for NP at the time of the study. Other reported symptoms included skin pain or sensitivity and secondary symptoms from itching (skin discoloration, lumps or bumps, bleeding or scabbing). NP-related itch was frequently reported to affect mood, interfere with sleep, and disrupt self-care. Limitations: Only English-speaking participants living in the United States were included. Conclusion: This study highlights the patient experience of living with NP and findings reveal that there remains an unmet need for effective therapeutic options to address NP-related itch.

Notalgia Paresthetica: Cervical Spine Disease and Neuropathic Pruritus.

Notalgia paresthetica (NP) is a dermatologic condition with predominant, primarily left unilateral pruritus and hyperpigmentation that typically occurs on the upper and middle back. The etiology remains largely elusive. A 57-year-old female with a history of neck pain presented with refractory NP since six months. Through diagnostic x-ray, cervical degenerative changes were discovered at the C5-C6 level, and she was prescribed a course of cervical traction. The cervical theory of NP is presented and is supported with x-ray findings in this case.

Therapeutic Use of Botulinum Neurotoxins in Dermatology: Systematic Review.

Botulinum toxin is a superfamily of neurotoxins produced by the bacterium Clostridium Botulinum with well-established efficacy and safety profile in focal idiopathic hyperhidrosis. Recently, botulinum toxins have also been used in many other skin diseases, in off label regimen. The objective of this manuscript is to review and analyze the main therapeutic applications of botulinum toxins in skin diseases. A systematic review of the published data was conducted, following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Botulinum toxins present several label and off-label indications of interest for dermatologists. The best-reported evidence concerns focal idiopathic hyperhidrosis, Raynaud phenomenon, suppurative hidradenitis, Hailey-Hailey disease, epidermolysis bullosa simplex Weber-Cockayne type, Darier's disease, pachyonychia congenita, aquagenic keratoderma, alopecia, psoriasis, notalgia paresthetica, facial erythema and flushing, and oily skin. Further clinical trials are still needed to better understand the real efficacy and safety of these applications and to standardize injection and doses protocols for off label applications.

Presumptive spondylogenic pruritus: a case study.

OBJECTIVE: To describe a case of a patient with chronic pruritus of the upper back and arms who underwent complete resolution of his complaint following a short course of chiropractic care. CASE PRESENTATION: A 36-year-old male suffering with chronic, severe pruritus affecting the upper back and both arms, presented for chiropractic treatment after pharmacological treatment and dietary restrictions failed to resolve his complaint. Physical examination revealed restrictions of thoracic and cervical intervertebral motion. However, radiological examination did not identify any substantial pathology of the spine. Following a short course of chiropractic treatment, which included spinal manipulation and home exercises, his complaint of pruritus resolved completely. SUMMARY: In this case, a severe and chronic complaint of pruritus which was refractory to other forms of care resolved quickly after the institution of chiropractic care. It is therefore hypothesized that the patient's pruritus was etiologically linked to biomechanical problems of the spine.

OBJECTIF: Décrire le cas d'un patient présentant un prurit chronique à la partie supérieure du haut du dos et aux bras qui est complètement disparu après une courte période de traitements chiropratiques. EXPOSÉ DU CAS: Un homme de 36 ans souffrant d'un prurit chronique grave à la partie supérieure du dos et aux deux bras s'est présenté à une clinique chiropratique après avoir suivi un traitement pharmacologique et un régime alimentaire qui se sont avérés infructueux. L'examen physique a révélé une limitation de la mobilité articulaire de la colonne dorsale et de la colonne cervicale. L'examen radiologique n'a révélé aucune pathologie grave de la colonne vertébrale. Après une brève période de séances chiropratiques par manipulations vertébrales et un programme d'exercices à domicile, le prurit est complètement disparu. RÉSUMÉ: Dans ce cas, un prurit grave et chronique, réfractaire à d'autres formes de traitement, est disparu rapidement après le commencement des traitements chiropratiques. On peut donc supposer que le prurit du patient était lié à des troubles biomécaniques de la colonne vertébrale.

[Clinical shortcuts in the differential diagnosis of pruritus]. / Klinische Shortcuts in der Differenzialdiagnostik von Pruritus.

Chronic pruritus is a common and burdensome symptom in medicine. The care of patients with chronic pruritus is very complex not only because of the high prevalence, but also because of the multifactorial character of itch and the lack of approved therapies. In addition to the main patient need to alleviate the pruritus, patients wish to find the cause of chronic pruritus. This article summarizes some clinical shortcuts. Simple procedures such as taking a detailed medical history can provide clues to the underlying cause of chronic pruritus in order to achieve targeted diagnostic workup or to avoid unnecessary testing. If clinical shortcuts are not identified, we recommend a structured medical history, which is also discussed in this article.

[Notalgia paresthetica: Treatment with botulinum toxin type A]. / Notalgia parestésica, tratamiento con toxina botulínica tipo A.

Notalgia paresthetica is a sensory mononeuropathy caused by compression localized in the dorsal region. The condition is clinically characterised by the presence of pruritus, paresthesias and hyperalgesia associated with a hyperpigmented patch in the correspondingt dermatoma, substantially impairing quality of life. We report the cases of two patients aged between 35 and 65years with chronic symptoms and treated in our service with botulinum toxin type A in the affected areas. We observed a decrease in the EVA pain scale and the intensity of the pruritus after infiltrations, as well as a reduction in the hyperpigmented patch at the first, third and sixth months after the intradermal injections that has been maintained after a year. We conclude that botulinum toxin typeA treatment could be a safe and useful alternative in these patients, as it has been shown to be effective over a longer term than available treatments to date, although further studies are required to confirm our findings.

Notalgia paresthetica: clinical features, radiological evaluation, and a novel therapeutic option.

BACKGROUND/OBJECTIVE: Notalgia paresthetica (NP) is a sensory neuropathy characterized by localized pruritus and pain, presenting with or without a well-circumscribed hyperpigmented patch in the upper back. Abnormal sensations, such as burning, numbness, and paresthesia are often present in patients with NP. In this study, we clinically and radiologically analyzed patients with NP. The literature contains studies describing lidocaine treatments involving intravenous and topical applications for NP. We also investigated the effect of intradermal lidocaine injection on patients with NP. METHODS: A total of 80 patients (45 patients with NP and 35 suffering from dorsalgia without NP) were included in the study. The age, gender and body mass index (BMI) of the patients, and the characteristics of their symptoms were recorded. The severity of pain and pruritus was assessed by the Visual Analog Scale (VAS). Radiography and magnetic resonance imaging of the spine were performed. In this study, we intradermally administered lidocaine diluted with saline into the upper back over three sessions. 1 cc 2% lidocaine was diluted with 5 cc 0.9% saline, and a total of 6 cc lidocaine mixture was obtained. The injection was performed locally at 1-cm intervals around the hyperpigmented patch and segmentally along the C2-T6 spinous processes. These patients were called for a follow-up at the second and fourth weeks and third month. RESULTS: There was no statistically significant difference between the two groups in terms of age, BMI, VAS-pain score, and duration of symptoms (p > 0.05 for all). Forty-six cervical and/or thoracic degenerative changes or herniated nucleus pulposus (HNP) were detected in patients with NP. There was a significantly higher number of HNP at the C6-7 segment and cervical degenerative changes in the NP group (p < 0.05). The VAS-pain and VAS-pruritus scores were significantly decreased at all follow-up sessions, and improvement was sustained by lidocaine up to the third month. CONCLUSION: Cervical degenerative changes and HNP of the C6-7 segment seem to be contributing factors for NP. Local lidocaine can be effective for pain relief and pruritus in NP.

Alleviation of notalgia paresthetica with duloxetine after several lines offailed treatment: A case report.

Chronic pruritus affects up to 20% of the population; about 8% of patients suffer from neurogenic pruritus, including notalgia paresthetica (NP). This is a syndrome of benign, chronic itch of the unilateral medial border of the scapula of unknown etiology and limited treatment efficacy. Here we report the background on NP, followed by a classic case presentation of a 63-year-old woman. We report on difficulty in her diagnosis and numerous failed lines of treatment, until initiation of treatment with duloxetine, which provided her with long-lasting benefit for the first time. Delay in diagnosis is common for NP, and though there are many options for treatment, evidence is lacking to support their efficacy. Finding an effective, well-tolerated regimen to alleviate long-term suffering brought on by this syndrome is heavily dependent on early identification. Our case provides anecdotal evidence for both treatment efficacy as well as the etiology of this poorly understood phenomenon.

Intralesional triamcinolone acetonide in notalgia paresthetica: Treatment outcomes in five patients.

Numerous treatment modalities have been tried with diverse results for pruritus due to notalgia paresthetica (NP). Corticosteroids suppress ectopic neural discharges from injured nerve fibers and also have short-lived suppressive effect on transmission in normal C-fibers. Herein, we evaluated the efficacy of intralesional triamcinolone acetonide in the treatment of NP. The medical reports of five patients who had been diagnosed with NP and treated with intralesional triamcinolone acetonide injections were retrospectively evaluated. Triamcinolone acetonide solution was injected intradermally (10 mg/mL; 0.1 mL/cm2 ) every 3 weeks for a maximum of four treatments. The severity of itch was scored by the patients on a combined numerical and visual analogue scale. After treatment, reduction in itch severity scores varied between 33% and 100%.

The etiology of notalgia paresthetica: a descriptive study of 117 patients.

BACKGROUND: Notalgia paresthetica (NP) is a neuropathic itching condition unilaterally localized in the midscapular area. It is a common but an underdiagnosed disease, and only a few studies investigating NP etiology with a limited number of patients have been reported in the literature. OBJECTIVE: We aimed to evaluate the demographic, clinical, histopathological, neurological, and radiological findings of NP patients and investigate correlations between them and symptoms of NP to elucidate the etiology of NP. METHODS: One hundred and seventeen consecutive patients diagnosed with NP were included and assessed in a multidisciplinary and prospective manner. We recorded demographic and clinical data and obtained a skin biopsy from the pruritic or hyperpigmented region. Pruritus severity was assessed by visual analogue scale (VAS). All patients were evaluated neurologically with magnetic resonance imaging. RESULTS: The mean age of the patients was 47.08 ± 12.28 years. The disease was more common in females (87.2%). Statistical analysis revealed that VAS scores were independent of the age, gender, and skin type of the patient. We found no significant difference in VAS scores between NP patients with or without comorbidities. Vertebral pathologies detected by MRI and amyloid deposition revealed in histopathology were not among the main factors affecting VAS scores. STUDY LIMITATION: Since consecutive patients enrolled into the study, we could not include equal number of male and female patients. CONCLUSION: We found no correlation between symptom severity and findings from neurological and histopathological evaluations. Further microneurological studies should be carried out to elucidate the etiology of NP.

Notalgia paresthetica: treatment review and algorithmic approach.

Background: Notalgia paresthetica (NP) is a sensory neuropathy of the back characterized by a well demarcated, hyperpigmented macule or patch located medial or inferior to the scapulae. Symptoms include localized pruritus and pain, and the clinical course consists of remissions and relapses. It can be an underrecognized and difficult disease to treat since conventional treatments for pruritus in inflammatory dermatosis have variable efficacy. There are a variety of treatment modalities, but strong evidence to suggest the superiority of any one treatment is lacking.Objective: This review describes the treatments that have been used for NP in the literature and evaluates their level of evidence with respect to their efficacy. We also present a treatment algorithm based on our analysis.Materials and methods: MEDLINE search was performed using the terms 'notalgia,' 'paresthetica,' and 'treatment.' All resulting articles have been included in this review.Results: Treatment options include topical agents (capsaicin, tacrolimus, anesthetic cream, and amitriptyline/ketamine), systemic agents (gabapentin, oxcarbazepine, and amitriptyline), procedural modalities (botulinum toxin A and narrowband UVB), and physical therapy.Conclusions: Treatment should begin with topical agents or physical therapy, then systemic agents, and finally procedural modalities. We recommend combining treatment options with physical therapy for sustained treatment response.

Dorsal scapular nerve neuropathy: a narrative review of the literature.

OBJECTIVE: The purpose of this paper is to elucidate this little known cause of upper back pain through a narrative review of the literature and to discuss the possible role of the dorsal scapular nerve (DSN) in the etiopathology of other similar diagnoses in this area including cervicogenic dorsalgia (CD), notalgia paresthetica (NP), SICK scapula and a posterolateral arm pain pattern. BACKGROUND: Dorsal scapular nerve (DSN) neuropathy has been a rarely thought of differential diagnosis for mid scapular, upper to mid back and costovertebral pain. These are common conditions presenting to chiropractic, physiotherapy, massage therapy and medical offices. METHODS: The methods used to gather articles for this paper included: searching electronic databases; and hand searching relevant references from journal articles and textbook chapters. RESULTS: One hundred-fourteen articles were retrieved. After removing duplicates, there were 57 articles of which 29 were retrieved. There were 26 articles and textbook chapters retrieved by hand searching equaling 55 articles retrieved of which 47 relevant articles were used in this report. DISCUSSION: The anatomy, pathway and function of the dorsal scapular nerve can be varied and exceptionally rarely may include a sensory component. The signs and symptoms, therefore, may include pain, atrophy, scapular winging, and dysesthesia. The mechanism of injury to the DSN is also quite varied ranging from postural to overuse in overhead work and sport. Other conditions in this area, including CD, NP, SICK scapula and a posterolateral arm pain pattern bear a striking resemblance to DSN neuropathy. CONCLUSION: DSN neuropathy should be included in the list of common differential diagnoses of upper and mid-thoracic pain, stiffness, dysesthesia and dysfunction. The study also brings forward interesting connections between DSN neuropathy, CD, NP, SICK scapula and a posterolateral arm pain pattern.

OBJECTIF: Ce document a pour objectif d'élucider cette cause peu connue de douleur dans le haut du dos par un examen narratif de la littérature, ainsi que de discuter du rôle possible du nerf scapulaire dorsal (NSD) dans l'étiopathologie d'autres diagnostics semblables dans ce domaine, y compris la dorsalgie cervicogénique (DC), la notalgie paresthésique (NP), l'omoplate SICK et un schéma de douleur postérolatérale au bras. CONTEXTE: La neuropathie du nerf scapulaire dorsal (NSD) constitue un diagnostic différentiel rare pour la douleur mi-scapulaire, costo-vertébrale et au bas/haut du dos. Il s'agit de troubles communs qui surgissent dans les cabinets de chiropratique, de physiothérapie, de massothérapie et de médecin. MÉTHODOLOGIE: Les méthodes utilisées pour rassembler les articles de ce document comprenaient la recherche dans des bases de données électroniques et la recherche manuelle de références pertinentes dans des articles de journaux et des chapitres de traités. RÉSULTATS: On a extrait 114 articles. Une fois les dédoublements éliminés, il y avait 57 articles, desquels 29 ont été extraits. Il y avait 26 articles et chapitres de traités extraits à la main, ce qui donne 55 articles extraits, desquels 47 articles pertinents ont été utilisés pour ce rapport. DISCUSSION: L'anatomie, la voie et la fonction du nerf scapulaire dorsal peuvent être variées et, exceptionnellement, comprendre un facteur sensoriel. Par conséquent, les signes et symptômes peuvent comprendre la douleur, l'atrophie, le décollement scapulaire et la dysesthésie. Le mécanisme de blessure du NSD est lui aussi très varié, allant de la posture au travail/sport au-dessus de la tête. D'autres troubles dans ce domaine, dont la DC, la NP, l'omoplate SICK et un schéma de douleur postéro-latérale au bras, ressemblent étrangement à la neuropathie du NSD. CONCLUSION: Il faut inclure la neuropathie du NSD dans la liste des diagnostics différentiels communs pour la douleur thoracique supérieure et médiane, la raideur, la dysesthésie et le dysfonctionnement. De plus, l'étude met en évidence d'intéressants liens entre la neuropathie du NSD, la DC, la NP, l'omoplate SICK et un schéma de douleur postéro-latérale au bras.

Notalgia Paresthetica of the Back Successfully Controlled by Pregabalin / 대한피부과학회지

Notalgia paresthetica (NP) is a chronic localized itch, affecting mainly the inter-scapular area particularly between the T2-T6 dermatomes. Occasionally it has a more widespread distribution and involves the shoulders, back, and upper chest. There are no specific cutaneous signs, apart from those attributed to scratching and rubbing. Various etiologies have been reported, but the cause of NP is not established. The current hypothesis regarding its etiology postulates that a neuropathic itch develops due to nerve entrapment of the posterior rami of spinal nerve arising at T2-T6. Another recent documented case showed an increase in the number of intradermal nerves by neural immunochistochemistry staining of S-100 protein, protein gene product 9.5 (PGP 9.5). Herein, we experienced an uncommon case of NP of the back and tried to clarify pathogenesis by using quantitative sensory testing, such as neurometer and Von-Frey filaments. Also, we performed neural immunochemistry to confirm an increase in nerve fibers at the site of the lesion.

Considerable Variability in the Efficacy of 8% Capsaicin Topical Patches in the Treatment of Chronic Pruritus in 3 Patients with Notalgia Paresthetica.

Notalgia paresthetica (NP) is a focal neuropathic itch condition manifesting in intense chronic or recurrent episodic itch in a hyperpigmented, macular, uni- or bilateral skin area located below and/or medially to the scapulae. Achieving satisfactory relieve in NP patients is challenging. In this case-series three female NP patients were treated with 8% capsaicin patches following a spatial quantification of their alloknetic area with a von Frey filament. The use of a von Frey filament in order to delimit the precise area of itch sensitization and thus patch application, proved clinically feasible. Although 8% topical capsaicin relieved itch in all three patients, the duration of the effectiveness varied greatly from only 3 days to >2 months. The treatment was well tolerated in the patients and there appear to be no significant hindrances to applying this treatment with NP as an indication, although it may only exhibit satisfactory effectiveness in certain patients. Placebo-controlled double-blinded trials are needed to confirm the effectiveness of the treatment and assess predictive parameters of the treatment outcome.

Neurocutaneous disease: Neurocutaneous dysesthesias.

Dysesthesia is a generic term for a cutaneous symptom--such as pruritus, burning, tingling, stinging, anesthesia, hypoesthesia, tickling, crawling, cold sensation, or even pain--without a primary cutaneous condition in a well-defined location that is often caused by nerve trauma, impingement, or irritation. There are multiple types of dysesthesias depending on the body location and the nerves involved. While location, exact symptoms, and etiologies might vary, the underlying theme is that these conditions are of neurologic origin and have dermatologic consequences. For many of these conditions, the symptoms are localized to the skin, and patients frequently present to the dermatologist; it is important for dermatologists to be knowledgeable about these symptoms and their underlying causes. In part II of this continuing medical education review, the primary diagnoses associated with underlying cutaneous dysesthesias will be explored, including scalp dysesthesia, trigeminal trophic syndrome, meralgia paresthetica, notalgia paresthetica, and brachioradial pruritus. The typical demographics in terms of symptoms, location, and patient populations will be discussed in addition to the specific etiologies, workups, and possible treatment options.
