Over the past 10 years, some physicians have begun using a chemical destructive technique that we call a neurolytic series of injections. Dr. McNamara believes that surgery should be performed only after failure of the neurolytic injection series.
There are five injections in the series, one given every two weeks. The effectiveness is not known until one month after the last injection has been given. Dr. McNamara finds that with ultrasound guidance, his success rate in achieving 100 percent resolution of symptoms occurs in 85 to 90 percent of cases.
