The Stellate Ganglion Block (SGB) is a medical procedure that involves injecting a local anesthetic into the stellate ganglion, a cluster of nerves located in the neck. Medical professionals commonly employ this procedure to treat various conditions, including chronic pain, post-traumatic stress disorder (PTSD), and certain types of headaches. In this blog post, we will delve into the mechanics of the Stellate Ganglion Block, its potential benefits, and associated risks.

Understanding the Stellate Ganglion Block

The stellate ganglion, located on either side of the voice box in the neck, consists of nerves that form part of the sympathetic nervous system. It regulates blood flow to the face, neck, and upper extremities while also controlling sweating and temperature in these areas.

The Stellate Ganglion Block entails injecting a local anesthetic, such as Ropivicaine, into the stellate ganglion to temporarily impede the transmission of signals to the brain, thus providing relief from various conditions. It is a minimally invasive outpatient procedure, allowing patients to return home on the same day.

Utilizations of the Stellate Ganglion Block

Treatment of Post-Traumatic Stress Disorder (PTSD)

PTSD can lead to an overactive fight-or-flight response, resulting in symptoms like hypervigilance, anxiety, and flashbacks. The stellate ganglion, integral to the sympathetic nervous system, governs these stress responses. By temporarily blocking the stellate ganglion, SGB aids in resetting this hyperactive response.

SGB has demonstrated its ability to diminish the intensity of PTSD symptoms, including intrusive thoughts and nightmares. It may also enhance a patient’s capacity to engage in therapeutic treatments, such as psychotherapy, by offering a temporary period of reduced physiological arousal. While not a standalone cure, SGB stands as a valuable tool within a comprehensive treatment plan for individuals grappling with PTSD, affording them respite from the overwhelming effects of their trauma.

Treatment of Long COVID

Long COVID, also known as post-acute sequelae of SARS-CoV-2 infection (PASC), refers to persistent symptoms experienced by some individuals after recovering from COVID-19. These symptoms encompass fatigue, brain fog, shortness of breath, and muscle pain, significantly impeding daily life activities.

The Stellate Ganglion Block holds promise in relieving long COVID symptoms by reducing inflammation and enhancing blood flow to affected areas through the interception of pain signals from the stellate ganglion. This can substantially restore a patient’s quality of life, facilitating a return to normal activities.

The Procedure

The Stellate Ganglion Block typically takes place as an outpatient procedure. Performed under local anesthesia, it allows patients to remain awake while numbing the targeted area, facilitating feedback for precise treatment.

During the procedure, the patient lies supine, extending their neck to expose the stellate ganglion. After cleaning the area, the healthcare provider administers a local anesthetic into the ganglion using a fine needle. Imaging techniques like fluoroscopy or ultrasound guide the injection to ensure accuracy.

The entire procedure typically lasts between 15 to 30 minutes. Following the injection, the patient undergoes a brief monitoring period to check for immediate complications. Although they can usually return home the same day, strenuous activities are advised against for a few days.

Potential Benefits and Risks

The Stellate Ganglion Block has garnered reports of significant relief for individuals grappling with PTSD, anxiety, parosmia, and long COVID. Many patients have conveyed improved symptoms, ranging from restored sense of smell to reduced fatigue and muscle pain, ultimately elevating their quality of life and enabling a return to normalcy.

As with any medical procedure, the Stellate Ganglion Block carries inherent risks, including infection, bleeding, nerve damage, and allergic reactions to the anesthetic. Nevertheless, these risks remain relatively rare, and when administered by a qualified healthcare professional, the procedure is generally considered safe. Prior to undergoing the procedure, patients should discuss these risks with their healthcare provider.


The Stellate Ganglion Block, a medical procedure, offers hope to individuals grappling with PTSD, parosmia, and long COVID. By intercepting pain signals from the stellate ganglion, this procedure can alleviate symptoms and improve quality of life. If considering a Stellate Ganglion Block, consult with a qualified healthcare provider to determine its suitability. It represents a promising treatment option, bringing relief to those enduring persistent symptoms.
