Tumescent Infiltration of Corticosteroids, Lidocaine, and Epinephrine Into Dermatomes of Acute Herpetic Pain or Postherpetic Neuralgia

Twenty-six patients with herpetic neuralgia were divided into 2 groups. Group 1 consisted of 13 patients with acute herpetic neuralgia, arbitrarily defined as pain beginning from 0 days to 3 months after the onset of herpes zoster infection. Group 2 consisted of 13 patients treated during the course of the postherpetic neuralgia, arbitrarily defined as pain lasting 3 months or more from the onset of the herpes zoster outbreak. Initial pain was scored subjectively by the patient on a scale of 0 to 10. Zero equaled no pain; 1 to 4, a level of pain that was annoying without having substantial effects on the patient’s lifestyle; 5 to 9, pain that affected normal routines and activities; and 10, unbearable pain that was extremely incapacitating.
