How Is Postherpetic Neuralgia Treated?

Nerve blocks: Nerve blocks are effective in the early stages of postherpetic neuralgia. Stellate nerve block, epidural nerve block, paravertebral nerve block, and nerve stem block can be selected based on the innervation of the pain site. It has been reported that within 3 months after the onset of herpes zoster, 70%-80% of patients can be relieved by sympathetic nerve block, but the effect of nerve block is significantly reduced in patients with prolonged refractory postherpetic neuralgia
