What relieves long-lasting pain after a shingles outbreak?

Postherpetic neuralgia, or PHN, is the persistence of shingles pain for more than a month after the shingles rash heals, explains WebMD. It is the most common complication of shingles, affecting up to 15 percent of those who develop shingles. Patients who begin taking antiviral medications such as acyclovir, famciclovir or valacyclovir within three days of developing the shingles rash are less likely to develop PHN.
