ObjectiveThe objective was to report on the possibility of allergic reaction to the components of a spinal cord stimulator.DesignWe describe a severe allergic reaction after the insertion of a spinal cord stimulator in a patient with complex regional pain syndrome type 1.SettingThe patient was being followed in an office-based pain management practice.PatientThe patient is a 41-year-old woman with complex regional pain syndrome type 1, posttrauma.InterventionInsertion of a cervical and lumbar spinal cord stimulator.Outcome MeasuresThe outcome measures were a numerical scale of pain intensity and the ability to perform the activities of daily living.ResultsAdequate pain control complicated by allergic reaction.ConclusionsThere exists a possibility that a patient may experience an allergic reaction to spinal cord stimulator components. Recognition of such contact sensitivity is important for physicians implanting such devices. Patients may be misdiagnosed as having infections, which can delay appropriate management; definitive diagnosis can be confirmed with a patch test. Treatment consists of removal of such devices.
