Stellate Ganglion Blocks (SGB) Therapy

Stellate Ganglion Block (SGB) can rapidly reduce symptoms of PTSD and trauma-related anxiety by calming the overactive “fight-or-flight” response, helping restore emotional balance and supporting recovery when conventional treatments have been ineffective.

By modulating the sympathetic nervous system, SGB helps quiet the brain’s overactive fear circuits, particularly the amygdala (brain's fear centre). This physiological calming allows patients to process emotions more effectively, improve sleep, and regain control over stress-related symptoms that perpetuate trauma responses.

Stellate Ganglion Block (SGB) can relieve certain chronic pain conditions, such as complex regional pain syndrome and nerve-related pain. SGB can reduce pain intensity and improve function when other treatments have provided limited benefit.

By targeting the sympathetic nervous system, SGB helps quiet nerve overactivity that amplifies pain signals. This can improve blood flow, reduce inflammation, and alleviate pain linked to nerve conditions or dysregulated stress responses, supporting long-term functional recovery.

While Stellate Ganglion Block (SGB) is best known for its use in PTSD and chronic pain, research shows it can also improve other conditions linked to the sympathetic nervous system.

By modulating the sympathetic nervous system, SGB can influence a wide range of body functions beyond pain and mood. Studies show benefits for conditions such as Ménière’s disease, menopausal hot flushes, and hyperhidrosis, where sympathetic overactivity contributes to persistent symptoms and autonomic imbalance.

Your Stellate Ganglion Block (SGB) begins with a comprehensive medical assessment, including questionnaires and a medical consultation, to review your history and assess suitability.

We explore your condition, explain the procedure, and design a tailored treatment plan, ensuring you understand the potential benefits, risks, and expected outcomes.

Once approved, the Stellate Ganglion Block (SGB) is performed as a day case in a hospital by a qualified interventional pain specialist. The procedure is completed under image guidance for accuracy and safety. An anaesthetist will also be present to administer IV sedation to ensure your comfort. 

Depending on your treatment plan, you may require a single injection or it may be part of a series of treatments across several weeks.

Once the procedure is completed, you will be monitored in a post-procedure recovery area until it’s safe for discharge — typically within two hours. 

Most patients can resume normal activities within 24 hours, though some temporary localised discomfort may occur.

We provide structured clinical follow-up, including medical review and questionnaire measures, to assess your response, address any concerns, and guide further care. 

Your ongoing plan may include repeat procedures, allied health support, or integration with other therapies for sustained improvement. We will coordinate with your broader care team for comprehensive support.
