Answer

It should be noted that whereas acute zoster pain and PHN are believed to result from different pathophysiologic mechanisms, it is clinically and experimentally impossible to determine precisely when the 2 types of pain cross over. Accordingly, some workers use the term zoster-associated pain to describe both acute and chronic pain as a continuum.
