The Effect of Erector Spinae Plane Block With and Without Addition of Magnesium on Relief of Pain from Post-herpetic Neuralgia.

Background: The best tool for management of postherpetic neuralgia (PHN) is a matter of debate. The use of ultrasound-guided erector spinae plane block (ESPB) in patients with PHN may decrease pain severity and the need for analgesics.

Objectives: The objective of this clinical study was to test the efficacy of ESPB with and without the addition of magnesium sulphate on pain control and analgesic consumption in patients with PHN.
