A stellate ganglion block (SGB) is a targeted injection that delivers anesthetic medication to a group of sympathetic nerves in the neck, helping to diagnose and treat pain conditions affecting the upper extremities. The stellate ganglion nerves, part of the sympathetic nervous system (SNS), play a critical role in regulating bodily functions such as heart rate, blood circulation, and temperature control.
Chronic pain can significantly impact daily life, making even simple tasks challenging. The stellate ganglion nerve plays a key role in transmitting pain signals, and by targeting this nerve cluster, an SGB can effectively interrupt pain pathways, offering relief for those struggling with conditions such as complex regional pain syndrome (CRPS), post-traumatic stress disorder (PTSD), and other SNS-related disorders. Patients who undergo this procedure often experience a noticeable improvement in their symptoms, enhanced mobility, and a better quality of life.
At PMIR Medical Center, our team of pain management specialists understands the complexity of chronic pain and the frustration of finding effective treatment options.
What Is a Stellate Ganglion Block?
A stellate ganglion block is a procedure that specifically targets the stellate ganglion, a bundle of sympathetic nerves located near the sixth and seventh cervical vertebrae. This nerve cluster forms from the fusion of the inferior cervical ganglion and the first thoracic ganglion. By delivering a local anesthetic to the stellate ganglion nerves, this treatment can interrupt pain signals and reduce symptoms associated with various chronic pain disorders.
The injection can relieve pain in the neck, head, upper chest, and upper extremities by calming the overactive sympathetic nervous system. Many patients with nerve injuries, circulation problems, and inflammatory conditions experience significant relief after undergoing a ganglion block.
The procedure is often recommended for individuals suffering from conditions such as complex regional pain syndrome (CRPS), trigeminal neuralgia, phantom limb pain, and shingles.
How Does a Stellate Ganglion Block Work?
The SGB procedure involves injecting a local anesthetic into the stellate ganglion nerve cluster. These nerves are responsible for transmitting pain signals from the upper body to the brain. By temporarily blocking these signals, the procedure can help alleviate chronic pain and other related symptoms. The anesthetic also promotes improved blood flow and can help restore normal function to the affected areas.
Many patients report immediate pain relief following a stellate ganglion block, though results can vary. Some individuals experience longer-lasting relief after multiple treatments. In addition to managing chronic pain, SGB has been explored as a potential treatment for posttraumatic stress disorder (PTSD) and anxiety disorders due to its ability to regulate the autonomic nervous system.
Stellate ganglion blocks are used to treat a variety of conditions due to their ability to interrupt pain signals and improve symptoms. A stellate ganglion block is an effective treatment for a variety of pain-related conditions. Patients who may benefit from this procedure include those with:
Complex Regional Pain Syndrome (CRPS)
A chronic pain condition that affects the limbs, often following an injury or surgery.
Trigeminal Neuralgia
A severe facial pain condition caused by nerve damage or compression.
Phantom Limb Pain
Persistent pain felt in a limb that has been amputated.
Shingles (Herpes Zoster)
A viral infection that causes nerve pain and inflammation.
Sympathetically Mediated Pain (SMP)
Pain that originates from the sympathetic nervous system, is often linked to nerve dysfunction.
Post-Traumatic Stress Disorder (PTSD)
Some studies suggest that a stellate ganglion block may help manage posttraumatic stress disorder (PTSD) symptoms by regulating the body’s stress response.
Circulatory Conditions
Raynaud’s disease and other disorders affecting blood flow may benefit from improved circulation following SGB.
Pain-Relieving Benefits of Stellate Ganglion Block
A stellate ganglion block offers several advantages for patients struggling with chronic pain. The procedure provides rapid relief for many individuals and is minimally invasive, making it a practical option for those seeking alternatives to long-term medication use.
By targeting the stellate ganglion nerves, the injection can significantly reduce pain, inflammation, and nerve-related discomfort. Many patients experience improved circulation and temperature regulation in the affected limbs, leading to a better overall quality of life. Additionally, the procedure can help identify the root cause of pain, allowing healthcare providers to develop more effective treatment plans.
Procedure Details
The stellate ganglion block is typically performed in an outpatient setting and takes approximately 15-30 minutes. Our physicians are highly trained in pain medicine, ensuring the procedure is performed with the utmost precision and care. During the procedure, the patient is positioned on their back or side while the neck area is cleaned and numbed with a local anesthetic. Using fluoroscopic or ultrasound guidance, a small needle is carefully inserted near the stellate ganglion to administer the anesthetic solution.
Patients may feel a warm sensation or temporary numbness in the treated area, which is a normal response to the injection. The effects of the anesthetic typically set in within 10-20 minutes. To evaluate the effectiveness of the treatment, patients are often asked to rate their pain levels before and after the procedure.
Recovery and Aftercare
Following a stellate ganglion block, most patients experience minimal side effects. Some individuals may have mild soreness or bruising at the injection site, but these symptoms usually resolve within a few days. It is recommended that patients rest for the remainder of the day and avoid strenuous activities. Driving is not advised immediately after the procedure, so arranging for transportation is necessary.
Although complications are rare, potential risks include temporary hoarseness, difficulty swallowing, or infection. Patients should follow post-procedure guidelines provided by their doctor to ensure a smooth recovery and optimal results.
