Abstract

Increasingly many studies have documented the clinical benefits of perineural injection therapy using 5% dextrose in water for various peripheral entrapment neuropathies. Postherpetic neuralgia is a condition involving chronic neuropathic pain caused by varicella-zoster virus, which may persist for an extended period despite continued treatment. This case series discusses three patients with postherpetic neuralgia who received ultrasound-guided subcutaneous injections with 5% dextrose, resulting in remarkable pain improvement.
