Stellate Ganglion Block

Pain Conditions Overview

What Are Stellate Ganglion Blocks?

Stellate(Cervical) Ganglion Block is a diagnostic procedure, which involves placing a local anesthetic such as Novocaine in or near the area of the spine that controls the sympathetic nerves.

The Stellate Ganglion is the name of the group of sympathetic nerves which control the arm and upper body.

Our pain providers will evaluate and diagnose if the root cause of pain is related to the sympathetic nerves consult with each patient to identify their discomfort level, pain level and any other related symptoms or concerns.

What are the Sympathetic Nerves?

The sympathetic nerves are a group of nerves that run in front of the spinal column. They are part of the autonomic nervous system and control many types of bodily functions such as sweating, blood pressure and digestion. Occasionally, these nerves can be injured causing pain. This can result in a condition known as Complex Regional Pain Syndrome or CRPS, formerly known as RSD or Reflex Sympathetic Dystrophy. Sometimes the injury can be minor such as a sprain.

Other causes of sympathetically mediated pain include Herpes Zoster or Shingles, Raynaud’s Disease, Phantom Limb Pain, Cancer, frostbite or other vascular problems.

How do I Know if the Sympathetic Nerves are the Cause of my Pain?

Pain from a problem in the sympathetic nervous system can be confined to an arm or leg or develop to include several body areas. The symptoms of a problem with the sympathetic nerves can be pain, which can be described as “burning” in nature. Sometimes, there is increased or decreased temperature in the affected area.

Often we may suggest a diagnostic procedure, which involves placing a local anesthetic such as Novocaine in or near the area of the spine that controls the sympathetic nerves. If, after the injection, the pain disappears or lessens then the sympathetic nerves may be a cause of your pain.
