Although the number of SARS-CoV-2 new cases may be declining due to the implementation of the vaccine in the USA, there is a rising cohort of people with long-term effects from the virus. These long-term effects include loss of taste, heart palpitations, and chronic pain syndromes. In this commentary, we assess the current literature to appraise the knowledge of long-term COVID-19 effects related to long-term pain syndromes including testicular pain, headache, chronic pain, and chest pain.

Background: Low back pain affects the lives of millions of people in the United States and the world. Not only does low back pain affect the quality of life for the individual patient, but it also accounts for many emergency department and health care visits. For a subset of patients, conservative measures such as medications and physical therapy, nonsurgical interventions, and surgery are not effective. Peripheral nerve stimulation is an emerging treatment option for patients with chronic low back pain. This case series assesses 6 patients' experiences with lumbar level peripheral nerve stimulation. Case Report: Three male and 3 female patients underwent lumbar level peripheral nerve stimulation as a treatment for chronic low back pain. The average age of the patients was 63.5 years, and they demonstrated an average pain reduction of 64.8%. Conclusion:This series provides evidence that lumbar level peripheral nerve stimulation may be an efficacious treatment for chronic low back pain that is refractory to conservative measures. Large studies are needed to assess the outcomes and durations of improvement associated with this treatment.

Background Genicular nerve radiofrequency ablation (RFA) is an effective, minimally invasive procedure often used to treat patients with intractable knee pain secondary to knee osteoarthritis and failed knee replacements. The prevalence of knee pain in adults has been estimated to be as high as 40% and is continuously increasing with an aging population. Over the past two decades, proceduralists have adopted variations in patient preparation, procedural steps, and post-operative care for genicular nerve RFA procedures. A survey was dispensed via the American Society of Pain and Neuroscience (ASPN) to gain a popular assessment of common practices for genicular nerve RFA. Methods A 29 question survey was dispensed via SurveyMonkey to all members of ASPN. Members were able to respond to the survey a single time and were unable to make changes to their responses once the survey was submitted. After responses were compiled, each question was assessed in order to determine common practices for genicular nerve RFA. Results A total of 378 proceduralists responded to the survey. There was high consensus with the three most commonly targeted nerves. The inferomedial, superomedial, and superolateral genicular branches were treated by 95–96% of respondents, while other targets were less commonly treated. There remains some debate among proceduralists regarding the need for a second diagnostic nerve block and the type of steroid used for diagnostic nerve blocks. Conclusion Pain physicians use a wide variety of methods to perform genicular nerve ablations. The data offered by the survey show that there is no standardized protocol when it comes to treating knee pain via genicular nerve block and ablation and highlights controversies among proceduralists that ought to serve as the targets of future clinical research aimed at establishing a standardized protocol.

Background: Intercostal neuralgia is pain associated with the intercostal nerves along the rib, chest, and upper abdominal wall. Intercostal neuralgia has various etiologies, and current conventional treatment options include intercostal nerve blocks, nonsteroidal anti-inflammatory drugs, transcutaneous electrical nerve stimulation, topical medications, opioids, tricyclic antidepressants, and anticonvulsants. For a subset of patients, these conventional treatment options provide little relief. Radiofrequency ablation (RFA) is an emerging procedure for the treatment of chronic pain and neuralgias. Cooled RFA (CRFA) is a specific type of RFA that has been trialed as a treatment for intercostal neuralgia in patients refractory to conventional treatment modalities. This case series assesses the efficacy of CRFA for the treatment of intercostal neuralgia in 6 patients. Case Series: Three female and 3 male patients underwent CRFA of the intercostal nerves to treat intercostal neuralgia. The patients had an average age of 50.7 years and demonstrated an average pain reduction of 81.3%. Conclusion: This case series suggests that CRFA may be an effective treatment option for patients with intercostal neuralgia that is not responsive to conservative treatment options. To determine the duration of pain improvement, large research studies need to be conducted.
