Varicella zoster virus (VZV) is a DNA virus that causes both primary and recurrent viral infections. Herpes zoster (HZ), also known as shingles, is a unique condition that is induced by VZV reactivation. Neuropathic pain, malaise, and sleep disruption are prodromal symptoms in such cases. Postherpetic trigeminal neuralgia is neuropathic pain caused by varicella-zoster virus (VZV) infection of the trigeminal ganglion or branches, which remains or reappears after herpes crusting. In this report, we present a case of trigeminal neuralgia of the V2 branch after herpes, exhibiting typical findings of unusual involvement of the trigeminal nerve. Notably, the patient was treated using electrodes placed through the foramen ovale.
