Lumbar Erector Spine Plane Block for Pain Management in Postherpetic Neuralgia in a Patient with Chronic Lymphocytic Leukemia

Postherpetic neuralgia (PHN) refers to the chronic neuropathic pain that persists beyond the initial varicella-zoster rash. Patients with chronic lymphocytic leukemia (CLL) are susceptible to infections because of decreased immunity. Various treatment strategies including pharmacological, nonpharmacological, and interventional techniques have been described in the literature. We report the successful management of PHN with lumbar erector spinae plane block in a patient of CLL.
