Stellate Ganglion Block for Complex Regional Pain Syndrome Treatment After SARS-CoV-2 Vaccine: A Case Report

Complex regional pain syndrome (CRPS) is a poorly understood neuropathic pain syndrome that may have different etiologies. Reports of this syndrome after vaccination are rare. We report a female patient with a medical history of acute stroke of the right carotid artery in the previous four months who developed hyperalgesia, allodynia, edema, and color changes in the upper left member compatible with CRPS one day after SARS-CoV-2 vaccination. A multimodal therapeutic approach was adopted, including a stellate ganglion block, with favorable results, including pain score reduction and increased mobility of the affected member.

Post-COVID-19 vaccination arm pain diagnosed as complex regional pain syndrome: A case report

As the vaccination efforts against the coronavirus disease-2019 (COVID-19) continue, more patients are likely to present with complications related to COVID-19 vaccination. We describe the first reported case of complex regional pain syndrome (CRPS), involving the upper extremities, that occurred after COVID-19 vaccination. The patient presented with acute-onset severe arm pain and swelling following vaccine administration. Based on the clinical, electrodiagnostic, and radionuclide three-phase bone scan findings, the patient was diagnosed with postvaccination CRPS. The COVID-19 vaccine possibly elicited an immune-mediated inflammatory response to the injected antigen in the patient, who was predisposed to CRPS due to inflammatory immunity. The COVID-19 vaccine elicited an immune-mediated inflammatory response to the injected antigen, resulting in CRPS following COVID-19 vaccination.
