Answer

See the list below:

  • The natural history of postherpetic neuralgia (PHN) involves slow resolution of the pain syndrome.

  • In those patients who develop PHN, most will respond to analgesic agents such as the tricyclic antidepressants.

  • A subgroup of patients may develop severe, long-lasting pain that does not respond to medical therapy. Continued research for new agents is necessary.
