Erythromelalgia is a rare hereditary channelopathy affecting the Nav1.7 sodium channel. Patients afflicted with this condition suffer from pain in their hands and feet, with vasomotor changes including flushing and redness to the distal upper and lower extremities. Current treatment modalities for this condition include pharmacological therapies (neuropathic medications), behavioural interventions, lumbar epidural infusions with local anaesthetics and sympathetic nerve blocks. Despite these treatments, many patients may have refractory pain. In these situations, there may be a role for dorsal column spinal cord stimulation for management of their pain. Here, we present the case of a 21-year-old man with 9-year history of refractory erythromelalgia successfully treated with paresthesia-free dorsal column spinal cord stimulation.
