The existent therapeutic options for post-herpetic neuralgia (PHN) are varied, albeit not sufficiently effective. The aim of this study was to try a new treatment modality for PHN. A spray of liquid nitrogen (LN) was used in 47 patients suffering from PHN as a stimulator of a mechanism not yet completely understood. ⋯ Before the sixth treatment session, good or excellent improvement was obtained in 94% of the study patients. Pain was eliminated with one session in nine patients (19%), and with two sessions in eight patients (17%). We conclude that this non-freezing technique is absolutely safe and injury-free, and is very efficient in calming PHN.
