Exclusion Criteria

• •Subject is pregnant and/or breast-feeding.
• •Subjects with additional sources of chronic pain will not be allowed if the severity of pain in additional locations is severe enough to compromise assessment of PHN pain. This will be left to the Investigator's discretion.
• •Subject has a medical condition, other than PHN, that is not well-controlled with treatment; or the subject has any clinically significant condition that would, in the opinion of the investigator, preclude study participation, interfere with the assessment of pain, or pose unacceptable risk to the participant.
• •Subject has been enrolled in another study within 30 days.
• •Subject has a known contact allergy to surgical skin markers.
• •In the judgment of the investigator, the subject has a psychiatric or psychological disorder that would interfere with the completion of the study, confound the study results, or pose patient risk.
• •Subject has neuropathy or nerve fiber disease other than PHN (e.g., diabetic peripheral neuropathy).
