How Stellate Ganglion Block (SGB) Offers Relief for PTSD, Pain, and Dysautonomia

If you’ve tried everything from medications and therapy to lifestyle changes and still feel stuck in a cycle of nervous system dysfunction, you’re not alone. At Interventional Orthopedics of Washington (IOW), we understand how exhausting and discouraging that can be. That’s why we offer targeted treatments like the Stellate Ganglion Block (SGB) to help restore calm, function, and hope.

SGB is a specialized, image-guided nerve block that can help reset an overactive sympathetic nervous system. For individuals suffering from post-traumatic stress disorder (PTSD), chronic pain conditions, or dysautonomia, this treatment offers a promising path toward relief.

What Is the Stellate Ganglion and Why Does It Matter?

The stellate ganglion is a bundle of sympathetic nerves located in the lower neck. These nerves influence automatic functions like:

1. Heart rate and blood pressure

2. Sweating and temperature regulation

3. Blood flow to arms and face

4. Fight-or-flight stress responses

Chronic trauma, stress, or illness can cause these nerves to stay hyperactive, keeping the body in a constant state of alert. This overdrive contributes to many symptoms associated with PTSD, chronic pain, and autonomic nervous system disorders.

What Is a Stellate Ganglion Block (SGB)?

The Stellate Ganglion Block (SGB) is a minimally invasive injection of local anesthetic near the stellate ganglion performed under ultrasound or fluoroscopy guidance. The injection temporarily "blocks" the sympathetic nerve signals, giving the nervous system a chance to reset and calm down.

During the procedure:

• Our specialists use real-time imaging for precise needle placement

• A local anesthetic is carefully injected near the stellate ganglion

• Most patients spend a short time in recovery before going home

Relief may begin within days and last from weeks to several months, depending on the individual.

How SGB Can Help with PTSD, Chronic Pain, and Dysautonomia

PTSD Relief

Post-Traumatic Stress Disorder (PTSD) involves more than just emotional distress. When the sympathetic nervous system is constantly activated, it can trigger:

• Panic attacks

• Nightmares and poor sleep

• Anxiety and hypervigilance

SGB may help by:

• Calming fight-or-flight responses

• Improving sleep and emotional balance

• Enhancing the effectiveness of therapy

Chronic Pain Conditions

Conditions like Complex Regional Pain Syndrome (CRPS) or neuropathic pain involve overactive nerves. SGB can:

• Reduce nerve pain and inflammation

• Improve motion and comfort

• Increase tolerance for rehab or physical therapy

Dysautonomia and POTS

Dysautonomia, including Postural Orthostatic Tachycardia Syndrome (POTS), causes symptoms like dizziness, fatigue, and irregular heart rate. SGB may help:

• Regulate heart rate and blood pressure

• Reduce lightheadedness and brain fog

• Improve daily function without added medications

Who Is a Good Candidate for SGB?

At IOW, we take time to evaluate your full medical history, imaging, and symptoms before recommending SGB as part of your care plan. We believe in multidisciplinary care that combines regenerative and functional medicine when appropriate.

SGB may be right for you if you:

• Have persistent symptoms of PTSD, CRPS, or dysautonomia

• Haven’t responded to therapy or medications

• Are in good overall health and open to non-surgical options

What to Expect During and After the Procedure

The procedure takes about 15 to 30 minutes and is done on an outpatient basis. You can return home the same day.

After the injection, you may notice:

• Mild numbness in the arm or face

• Eyelid droop (Horner’s Syndrome), which is temporary

• Slight soreness or bruising at the injection site

Many patients begin to feel better within a few days. Depending on your condition, one injection may be enough, or a series may be recommended.

You can return to most normal activities right away, though we suggest avoiding heavy activity for 24–48 hours.

Is Stellate Ganglion Block Safe?

SGB is considered low-risk when performed by trained specialists. At IOW, we use advanced imaging to ensure safety and accuracy.

Rare risks include:

• Temporary swallowing difficulty or hoarseness

• Infection or bleeding at the injection site

• Nerve irritation

You’ll receive full pre- and post-care instructions so you can feel confident and supported throughout the process.
