Sympathetic Nerve Block

A cervical nerve block is usually performed when the patient is suffering from shoulder, arm, hand and/or neck pain. A block is used to determine if there his damage to the sympathetic nerve chain and if the damage is the source of the pain. Although this is a diagnostic test, it may provide relief far in excess of the duration of an anesthetic.

The purpose of the nerve block is to find out if your sympathetic nerves are causing your pain. The injection blocks the Sympathetic nerves. This may reduce pain, swelling, color, and sweating changes in the lower extremity and may improve mobility. It is the treatment for Reflex Sympathetic Dystrophy Syndrome (RSDS), Sympathetic Maintained Pain, Complex Regional Pain Syndrome (CRPS) and Herpes Zoster (shingles) involving the lower extremities.

During this injection, a corticosteroid (anti-inflammatory medicine) is injected into the epidural space, along with a local anesthetic. It’s called a nerve block injection because the needle is positioned next to an individual nerve root and is placing medication directly along the inflamed nerve root. A selective nerve root block will determine if that specific nerve is causing your pain.

The procedure takes less than a few minutes, we will monitor your movements, and then you will be released home with a pain diary to record your daily pain. This information will help your physician determine how well the injection worked. Pain relief duration can vary depending on the extent of inflammation on your facet joint.
