Stellate Ganglion Block

Alleviate physical symptoms of mental trauma and anxiety.

What is a Stellate Ganglion Block?

A Stellate Ganglion Block (SGB) is a minimally-invasive injection that resets the sympathetic nervous system. This more advanced version administers local anesthetic into the Stellate Ganglion nerve bundle and the Superior Cervical Ganglion.

What can a Stellate Ganglion Block do for you?

A SGB can quickly and effectively diminish mental and physical symptoms associated with mental trauma and anxiety by resetting the sympathetic nervous system.

The Sympathetic Nervous System influences significant body functions, including heart rate, blood pressure, and digestion. It also plays a key role in reacting to danger or stress by initiating a heightened fight-or-flight response. Once danger or stress passes, the nervous system is supposed to revert to its more neutral, standard state, but sometimes it gets stuck in fight-or-flight mode, perpetuating the symptoms we associate with stress and mental trauma, including:
  • Increased heart rate
  • Increased blood pressure
  • Fatigue
  • Nausea
  • Neurocognitive disorders
  • Headaches
  • DSBs give an overactive nervous system the chance to rest and reset

What can a SGB treat?

  • Post-Traumatic Stress Disorder
  • Anxiety
  • Long-COVID

Post-Traumatic Stress Disorder (PTSD) is brought on by a physically or emotionally traumatic life event. Today, the CDC defines trauma as an experience marked by a sense of horror, helplessness, serious injury, or the threat of serious injury or death.

Anxiety refers to persistent feelings of fear and dread that are not always triggered by a single, identifiable source. Anxiety often prompts physical changes, like: increased blood pressure, rapid heart rate, excessive sweating, dizziness, headaches, pain, and sleep irregularities.

Some common Long COVID symptoms—fatigue, oxygen deficiency, and brain fog—are related to nervous system dysfunction. By bringing the nervous system down from a heightened fight-or-flight state, DSBs can rapidly alleviate nervous system-related symptoms.

Common Questions

Should Stellate Ganglion Blocks replace therapy?

Stellate Ganglion Blocks complement psychotherapy. By giving your nervous system a chance to reset, the Block can actually help patients break through barriers in their talk and cognitive behavioral therapy sessions.

Do Stellate Ganglion Blocks hurt?

Most patients do not report pain, but because the Block is an injection you may experience brief and mild discomfort.

Will I experience side effects?

Following treatment, some patients experience some eyelid droopiness, redness, and congestion. Don’t worry—these are actually good signs, as they indicate that the sympathetic nervous system has been successfully reset. These effects typically diminish within 8 hours of treatment.
