A selective nerve block is a minimally invasive procedure used to identify and treat pain coming from a specific nerve or nerve root. A small amount of medication, often a local anesthetic with an anti-inflammatory medication, is injected near the targeted nerve. The procedure may be performed using imaging guidance to help accurately place the medication in the intended area.
A selective nerve block can provide temporary pain relief and may also help your healthcare provider determine which nerve is contributing to your symptoms. Relief varies from person to person and may last from hours to months depending on the underlying condition and treatment used. The procedure is commonly considered for certain types of neck, back, arm, or leg pain when a specific nerve is suspected to be involved.
