The mechanism
When the alarm won't switch off
Your sympathetic nervous system drives the fight-or-flight response — heart racing, senses sharpened, body braced for threat. It's life-saving in a real emergency. But after chronic stress, trauma, or hormonal upheaval, the system can get stuck in the "on" position, flooding the body and brain with stress signals long after the danger is gone.
The stellate ganglion is a cluster of sympathetic nerves in the side of the neck — a relay station for those alarm signals on their way to the brain. A stellate ganglion block bathes that relay in local anesthetic, briefly quieting it so the nervous system can re-set toward a calmer baseline.
How the procedure works
A few minutes, guided by ultrasound
SGB is a long-established outpatient procedure first developed for pain. Its use for stress-related and menopausal symptoms is a newer, evidence-driven application performed by trained physicians.
Pinpoint
You recline with your neck slightly extended. Ultrasound guides the physician to the stellate ganglion, avoiding nearby vessels and nerves.
Inject
A small dose of local anesthetic is placed at the ganglion. The injection itself usually takes only a few minutes.
Reset
A temporary drop in the eyelid and a warm, flushed hand confirm the block worked. You rest briefly, then go home the same day.
What it may help
One common thread, many applications
Each of these involves a sympathetic nervous system turned up too high. By calming that signal, SGB has shown promise across a growing body of clinical research.
Anxiety
For generalized anxiety and chronic stress, calming the body's alarm can lower the physical and mental intensity that fuels worry.
PTSD
The most studied use. By interrupting the trauma-driven alarm loop, SGB can rapidly ease hyperarousal, often within days of treatment.
Depression
Often tangled with anxiety and trauma. Early studies suggest improvement in depressive symptoms when the underlying alarm state settles.
Menopause
A non-hormonal option for hot flashes and night sweats — useful for women who can't or prefer not to use hormone therapy.
Sports performance & recovery
Athletes live in a high-sympathetic state. By nudging the autonomic system back toward balance, SGB is being explored as a way to calm pre-competition arousal, steady sleep, and support recovery from the physical toll of hard training.
Life after a GLP-1
Coming off a GLP-1 can bring back food noise along with real anxiety and stress as the body readjusts. SGB won't change appetite or weight, but by calming an over-activated nervous system it may help ease the anxiety and disrupted sleep that make the transition harder.
Is it right for you?
Who is a great candidate
- You live with PTSD, chronic anxiety, or trauma-related hyperarousal — a body that feels "always on."
- You've tried therapy and/or medication and want faster relief or fewer side effects.
- You notice the physical signs of fight-or-flight: racing heart, poor sleep, hypervigilance, a jumpy startle.
- You're peri- or postmenopausal with disruptive hot flashes or night sweats — especially if hormone therapy isn't an option.
- You're navigating life after a GLP-1 — working with the return of food noise, anxiety, and stress as your body readjusts.
- You want a rapid-acting boost that makes therapy and daily life easier to engage with.
- You're an adult who can be medically cleared for a neck injection.
A partner to therapy, not a replacement
SGB works best alongside trauma-focused therapy, counseling, and good medical care — not instead of them. It can lower the volume on the alarm so that other treatments have room to take hold.
A consultation determines whether SGB is appropriate for you, including review of medications, bleeding risk, and any conditions that make the injection unsuitable.

The stellate ganglion block is a well-established procedure for pain; its use for anxiety, PTSD, depression, and menopausal symptoms is considered off-label and is supported by emerging but still-evolving evidence, including some randomized trials with mixed results. Outcomes vary from person to person, and SGB is not a cure. Cited figures reflect findings from published case series and trials and are not a promise of individual results. Only a qualified physician can determine whether this procedure is appropriate for you after a full evaluation. Talk with your healthcare provider before making treatment decisions.
