What are Nerve Blocks?

Nerve Blocks, is a general term used to refer to the injection of local anesthetic (with or without steroids) onto or near nerves for temporary control of pain. It can also be used as a diagnostic tool to identify specific nerves as pain generators. Permanent nerve block can be produced by destruction of nerve tissue.

Therapeutic Uses

Nerve blocks can help patients who suffer from lower back pain, neck pain, sciatica (from a herniated disc), shingles, cancer, and painful peripheral vascular disease. It can also be used in the treatment of chronic face pain, dental pain, temporomandibular disorders (TMJ) and headaches.

Procedure Overview

Peripheral nerve blocks are achieved by combining a local anesthetic (such as lidocaine) a steroid (corticosteroid). Steroids are often used to reduce inflammation. Injection nerve blocks can be either single treatments or multiple injections over a period of time. Permanent nerve block can be effected using other drugs or methods including alcohol or phenol to selectively destroy nerve tissue, cryoanalgesia to freeze nerves, and Radiofrequency ablation to destroy nerve tissue using heat. Nerve blocks are sterile procedures that are usually performed in an outpatient facility. The procedure can be performed with the help of an ultrasound, EMG guidance or fluoroscopy (live x-rays).
