The pain is generally very severe and treatment can be extremely challenging, especially in the pediatric and adolescent population. We report a series of three cases of primary EM in pediatric patients involving the lower extremities, refractory to medical treatment that responded favorably to computed-tomography-guided lumbar sympathetic blockade. There was a significant improvement in pain scores, quality of life, and overall function as well as decreased analgesic requirements. Lumbar sympathetic blockade should be considered as a therapeutic modality in pediatric and adolescent patients with EM who are refractory to other treatments. Keywords: primary erythromelalgia, secondary erythromelalgia, computed tomography guided, lumbar sympathetic blockade
