Treatment of post-herpetic neuralgia. A review of 77 consecutive cases.

The treatment of 77 consecutive cases of post-herpetic neuralgia is reviewed. Stellate blockade proved helpful in 75% of patients with pain of less than 1 year's duration; 40% became virtually pain free. Drug treatment and electrical counterirritation methods gave improvement in 60% of cases but only 15% became pain free. Stellate block carried out after 1 year of pain proved helpful in only 44% of patients, and only 22% became pain free. Stellate blockade carried out within 1 year of the onset of symptoms would appear to be one of the treatments of choice for post-herpetic neuralgia. It would be of interest to see the results of a controlled randomised trial.
