What is a stellate ganglion block?
A stellate ganglion block places local anesthetic near a sympathetic nerve structure in the lower neck. It has long-standing medical uses and is now being studied for trauma-related symptoms, anxiety, dysautonomia and some pain conditions. Ultrasound guidance helps identify anatomy and guide a precise path.
Why might it affect trauma-related symptoms?
One hypothesis is that temporarily interrupting sympathetic signaling may help shift an over-activated autonomic pattern. That does not mean memories disappear or psychotherapy becomes unnecessary. Some people describe reduced hyperarousal, better sleep or more room to engage in other treatment.
A window is not the whole house.
When SGB helps, we view the response as an opportunity to strengthen sleep, movement, psychotherapy, medication strategy and other supports—not as proof that every symptom had one cause.
What does the research say?
Trials and reviews report encouraging improvement in several PTSD symptom measures, particularly hyperarousal and reactivity. The research base is still growing, especially for anxiety, dysautonomia and pain, which is why we pair careful screening with clear goals and thoughtful follow-up.
Who needs careful screening?
We review diagnosis, medications, bleeding risk, anatomy, prior procedures, cardiovascular and respiratory concerns, current mental-health care and the ability to complete follow-up. We also discuss alternatives and the specific symptoms by which we would judge response.
What happens after?
Expected temporary effects and procedure-specific risks are reviewed during consent. Follow-up focuses on symptom clusters, function and duration of change. Depending on response, the plan may involve no further procedure, a staged discussion or stronger emphasis on other care.
