Pudendal neuralgia (PN) involves severe, sharp pain along the course of the pudendal nerve, often aggravated with sitting. Current therapies include medication management, nerve blocks, decompression surgery, and neuromodulation. The ideal management for PN has not been determined. ⋯ PRF is a relatively new procedure and is felt to be safer than continuous radiofrequency. Current literature suggests that PRF delivers an electromagnetic field, which modifies neuro-cellular function with minimal cellular destruction. We conclude that PRF of the pudendal nerve offers promise as a potential treatment of PN that is refractory to conservative therapy.

Diagnosis is a critical component of health care. The world of diagnostic tests is highly dynamic. New tests are developed at a fast pace and technology of existing tests is continuously being improved. ⋯ Interventional techniques as a diagnostic tool in painful conditions is important due to multiple challenging clinical situations, which include the purely subjective nature of pain and underdetermined and uncertain pathophysiology in most painful spinal conditions. Precision diagnostic blocks are used to clarify these challenging clinical situations in order to determine the pathophysiology of clinical pain, the site of nociception, and the pathway of afferent neural signals. Part 5 of evidence-based medicine (EBM) in interventional pain management describes the various aspects of diagnostic accuracy studies.

Ethical and legal considerations in pain management typically relate to 2 issues. The first refers to pain management as a human right. The second involves the nature of the patient-physician relationship as it relates to pain management. ⋯ Absent a universal duty, no universal right exists. Pursuing pain management as a fundamental human right, although laudable, may place the power of the government in the middle of the patient-physician relationship. Despite apparent altruistic motives, attempts to define pain management as a basic human right could have unintended consequences, such as nationalization of medicine to ensure provision of pain management for all patients.

Case Reports
Serial stellate ganglion blocks for intractable postherpetic itching in a pediatric patient: a case report.
While intractable itching may be rarely associated with postherpetic neuralgia, it can have catastrophic complications if present. ⋯ The use of serial stellate ganglion blocks may be a treatment option for patients with intractable itching and postherpertic neuralgia of the neck and arm region. This technique may lead to more permanent solutions such as pulse radiofrequency lesion or chemical neurolysis of sympathetic ganglions for postherpetic itch.

The intervertebral disc has been implicated as an etiology of chronic lumbar spine pain based on clinical, basic science, and epidemiological research. However, there is lack of consensus regarding the diagnosis and treatment of intervertebral disc disorders. Based on controlled evaluations, the lumbar intervertebral discs have been shown to be sources of chronic back pain without disc herniation in 26% to 39%. Lumbar provocation discography, which includes disc stimulation and morphological evaluation, is often used to distinguish a painful disc from other potential sources of pain. Despite the extensive literature, controversy continues about provocation lumbar discography. ⋯ Based on the current systematic review, lumbar provocation discography performed according to the IASP criteria with control disc (s) with minimum pain intensity of 7 of 10, or at least 70% reproduction of worst pain (i.e. worst spontaneous pain of 7 = 7 x 70% = 5) may be a useful tool for evaluating chronic lumbar discogenic pain. Discography is an important imaging and pain evaluation tool in identifying a subset of patients with chronic low back pain secondary to intervertebral disc disorders.
