Summary
Postherpetic neuralgia (PHN) is a common condition and affecting 5 to 30% of the herpes zoster patients. In some cases, the pain remained refractory after first and second line treatment for herpes zoster. This suggests that there may be genetic variants that make some patients susceptible to PHN. Using saliva samples from herpes zoster patients the investigators are going to analyze the relationship between single nucleotide polymorphisms (SNPs) in genes that are known to be involved in pain and PHN.
