The FDA recently approved a new non-narcotic patch for the treatment of postherpetic neuralgia, a very painful complication of a shingles infection. The name of the new patch is Qutenza and it contains 8% capsaicin, a substance found in chili peppers that causes a burning sensation when applied.

The interesting thing about this treatment is application of the patch to the affected skin for just 1 hour can actually give up to 12 weeks of pain relief.
