Chronic pain conditions that involve the nervous system can be complex and difficult to treat. Sympathetic ganglion blocks are specialized pain management injections designed to diagnose and treat pain that originates from or is maintained by the sympathetic nervous system. These minimally invasive procedures can provide significant pain relief and help improve daily function.
If chronic pain is interfering with your quality of life, sympathetic ganglion blocks may be an effective treatment option. To learn more, call (215) 201-4569 or contact us online to schedule a consultation.
What Are Sympathetic Ganglion Blocks?
Sympathetic ganglion blocks are injections that target clusters of nerves known as sympathetic ganglia, which are part of the autonomic nervous system. These nerves regulate involuntary functions such as blood flow, sweating, and pain signaling.
By injecting anesthetic medication near the affected ganglion, the procedure temporarily blocks pain signals, helping physicians determine whether the sympathetic nervous system is contributing to the patient’s pain.
Conditions Treated with Sympathetic Ganglion Blocks
Sympathetic ganglion blocks are commonly used to diagnose and treat a variety of chronic pain conditions, including:
● Complex Regional Pain Syndrome (CRPS)● Chronic nerve pain● Post-surgical pain● Post-traumatic pain● Peripheral neuropathy● Circulatory pain disorders● Certain types of facial or abdominal pain
These blocks are often used when other conservative treatments have not provided sufficient relief.
Types of Sympathetic Ganglion Blocks
The specific type of block performed depends on the location of pain. Common sympathetic ganglion blocks include:● Stellate Ganglion Block – used for pain in the head, neck, arms, or upper chest● Lumbar Sympathetic Block – used for pain in the lower back, hips, legs, or feet● Celiac Plexus Block – used for abdominal or visceral pain
Your pain management specialist will determine the most appropriate block based on your symptoms and diagnosis.
How Do Sympathetic Ganglion Blocks Work?
The procedure is performed using advanced imaging guidance to ensure precise needle placement. Once the needle reaches the targeted ganglion, a local anesthetic—sometimes combined with anti-inflammatory medication—is injected.
If pain relief occurs following the injection, it confirms that the sympathetic nervous system plays a role in the pain. Relief may last from hours to weeks, and repeated injections may provide longer-lasting benefits.
Benefits of Sympathetic Ganglion Blocks
Sympathetic ganglion blocks may offer several benefits, including:
● Reduced chronic pain● Improved blood flow and circulation● Decreased inflammation● Improved mobility and function● Diagnostic insight into the source of pain
These injections are often part of a comprehensive pain management plan that may include physical therapy, medications, or additional interventional treatments.
What to Expect After the Procedure
Sympathetic ganglion blocks are typically performed on an outpatient basis. Most patients experience minimal discomfort and are able to return home the same day. Temporary side effects such as mild soreness or warmth in the treated area may occur but usually resolve quickly.
