Topical aspirin in chloroform and the relief of pain due to herpes zoster and postherpetic neuralgia.
To determine pain patterns and relationships in patients with herpes zoster and postherpetic neuralgia before and after topical application of aspirin dissolved in chloroform applied to the painful skin surface. ⋯ Topical aspirin dissolved in chloroform is an effective means of reducing pain due to herpes zoster and postherpetic neuralgia in most patients. The locus of pain origin and analgesia induced by topical aspirin is most likely at cutaneous free-nerve ending pain receptors. The mechanism responsible for the analgesic properties of aspirin is probably not the same as that responsible for its anti-inflammatory properties.
