Polyarteritis nodosa (PAN) can cause multiple neuropathies due to ischemia of the vasa nervorum, sometimes resulting in neuropathic pain. Reports on treating PAN-related pain are limited as it is a rare condition. We report a case where spinal cord stimulation (SCS) was effective in managing refractory pain in a patient with PAN. The patient, a male in his 60s, achieved remission following immunosuppressive therapy, but severe limb pain persisted. While conservative treatments improved the pain in his hands, the pain in his feet remained intense (NRS 10/10), causing difficulty walking and frequent nighttime awakenings. SCS implantation provided immediate relief (NRS 10/10 to 2/10), improving his walking speed and eliminating pain-related sleep disturbances. Six months post-implantation, the patient remained free of complications, with sustained pain relief (NRS 2–3/10).
