Acute Worsening of Clinical Presentation in CRPS after SARS-CoV-2 (COVID-19) Vaccination: A Case Series

Abstract

We present the acute worsening of clinical presentation in complex regional pain syndrome (CRPS), following mRNA-based COVID-19 vaccination. We report the case series of three patients diagnosed with CRPS type I who presented with acute worsening of symptoms after mRNA-based COVID-19 vaccination and their medical management. The acute clinical worsening after mRNA-based COVID-19 vaccination was transient and effectively managed with adjustment of individualized therapy in all three patients. The mortality and morbidity of COVID-19 infection are serious, and vaccination is recommended in the general population, including patients with a diagnosis of CRPS. However, clinicians should be aware of the possibility that there may be a clinical worsening CRPS after mRNA-based COVID-19 vaccination.

Lay abstract

This case series presents the worsening of symptoms in complex regional pain syndrome (CRPS), following mRNA-based COVID-19 vaccination. We report on three patients diagnosed with CRPS who presented with worsening of symptoms after mRNA-based COVID-19 vaccination and their medical management. The worsening of symptoms was temporary and managed with adjustment of individualized therapy in all three patients. The dangers of COVID-19 infection are serious, and vaccination is highly recommended in the general population, including patients with a diagnosis of CRPS. However, healthcare providers should be aware of the possibility of clinical worsening of CRPS after mRNA-based COVID-19 vaccination.
