Nerve stimulation is sometimes used as an alternative treatment for postherpetic neuralgia. This involves using electrodes to deliver tiny electrical shocks to the areas being affected. It is painless, and you control the electrodes by switching them on when you start experiencing pain. It is unclear why this treatment actually works, and it is not suitable for everyone. Certain creams and lotions may help as well. A lotion made from chili peppers called capsaicin or an aspirin-cream combination can relieve pain when rubbed into the affected area.
