Abstract

A pregnant patient with chronic regional pain syndrome (CRPS) and indwelling spinal cord stimulator presented with twin gestation for induction of preterm labor due to preeclampsia. Intravenous magnesium was initiated and a lumbar epidural catheter was placed uneventfully for labor analgesia. The patient reported complete relief of her CRPS-associated pain during and for 24 hours after delivery, while receiving intravenous magnesium, with her pain symptoms returning shortly after discontinuing magnesium. To our knowledge, there are no case reports that describe CRPS-associated pain relief while on peripartum magnesium therapy.
