There’s a kind of distress that doesn’t respond to insight alone. You understand your patterns. You’ve done therapy. You may even feel that, logically, things should be okay. And yet your body tells a different story—tight, vigilant, restless, bracing for something that never arrives.
Patients describe it in different ways: “I feel wired all the time.” “My body won’t calm down.” “Even when life is fine, I’m not.” This is often a reflection of how the nervous system has adapted—and, at times, become stuck.
Under periods of stress or trauma, the body activates a protective response: heart rate increases, muscles tense, attention narrows. This is the sympathetic nervous system—what most people know as “fight or flight”—and it protects us when activated under appropriate conditions. Once the threat passes, the system relaxes. However, for some individuals, it doesn’t fully turn off. The system remains elevated—subtly or intensely—leading to persistent anxiety or panic, hypervigilance, rumination, sleep disruption, irritability, emotional reactivity, or a sense of being “on edge” without a clear reason.
In these cases, the issue isn’t just psychological. It’s physiological.
What Is a Stellate Ganglion Block?
A Stellate Ganglion Block (SGB) is a targeted injection performed in the neck that temporarily reduces sympathetic activity and can help recalibrate a nervous system that has been operating in a state of high alert. It has been used for decades in pain medicine—particularly for conditions like complex regional pain syndrome, migraines, and chronic fatigue syndrome. More recently, it’s been explored as a way to help regulate an overactive stress response, especially in trauma-related conditions.
Using ultrasound guidance, a small amount of local anesthetic is delivered near the stellate ganglion—a cluster of nerves involved in sympathetic signaling. The goal is not sedation or numbing in the traditional sense, but rather to shift how the nervous system fires.
A Different Way to Think About It
Rather than thinking of SGB as “treating anxiety,” it may be more helpful to think of it as recalibrating a nervous system that has been operating in a prolonged state of alarm.
Some patients notice a sense of physical calm they haven’t felt in years, improved sleep, reduced reactivity to triggers, and a quieter internal baseline. Others notice something subtler: “I’m still me… but I’m not as activated.” The response isn’t always immediate or dramatic. Many patients describe it as feeling more settled—less edge, less reactivity, and a greater sense of ease in their body.
Why This Matters—Especially If You’ve “Done the Work”
One of the more frustrating experiences patients often share is “I understand everything… but my body doesn’t follow.” That gap between insight and physiology is where treatments like SGB can be helpful.
Therapy builds awareness. Practices build capacity. Ketamine helps rewire patterns. But when the nervous system is persistently overactivated, it can be difficult to access any of those tools in real time.
By resetting the baseline level of activation, SGB may make it easier to engage in therapy more effectively, feel safer in your body, and respond instead of react. It doesn’t replace the work—but it can make the work more accessible. For a deeper look at how ketamine supports this kind of neurological rewiring, our post on Stellate Ganglion Block and Ketamine Therapy: A Synergistic Approach to Patient Transformation explores how these two treatments can work together.
A More Complete Approach: Reset, Rewire, Regulate
At our practice, we think about healing in three complementary ways:
- Reset — helping the nervous system come out of a prolonged stress response
- Rewire — creating the conditions for new patterns and perspectives to emerge
- Regulate — strengthening the brain’s ability to maintain stability over time
Different treatments support different parts of this process. A stellate ganglion block often fits into that first category—recalibrating a system that has been operating in a state of high alert. For some people, that shift alone is meaningful. For others, it becomes a starting point—making it easier to engage in deeper work, whether that’s therapy, ketamine, or neuromodulation approaches like TMS therapy.
Beyond Mental Health: Where Else SGB Is Used
While interest in SGB has grown in the context of trauma and anxiety, it’s important to recognize that this is not where the procedure started. SGB has a long history in pain and cardiovascular medicine, where it has been used to address conditions involving the sympathetic nervous system, including:
- Complex Regional Pain Syndrome (CRPS) — where abnormal nerve signaling contributes to severe, persistent pain
- Chronic neuropathic pain — including conditions such as trigeminal neuralgia and post-herpetic neuralgia
- Migraines and certain headache syndromes — where autonomic and vascular factors may play a role
- Vascular conditions such as Raynaud’s phenomenon — where blood flow to the extremities is affected by sympathetic tone
- Central sensitization syndromes — where the nervous system becomes amplified and over-responsive to stimuli
- Autonomic disorders — where regulation between sympathetic and parasympathetic systems is disrupted
- Post-viral and dysautonomia-related conditions, including Long COVID and chronic fatigue syndrome (CFS/ME) — where persistent nervous system dysregulation may contribute to symptoms such as fatigue, brain fog, and exercise intolerance
In these settings, the goal is similar — to reduce excessive sympathetic activity and improve how the body is functioning at a physiologic level.
What to Expect
The procedure itself is brief and performed in a monitored setting.
Common temporary effects include:
- a drooping eyelid or redness in the eye (a known, expected sign that the block has taken effect)
- a sensation of warmth
- mild soreness at the injection site
These effects typically resolve within hours. As with any medical procedure, there are risks, and not everyone is a candidate. A thorough consultation is an important part of determining whether this is an appropriate option.
If you’ve been feeling like your system is constantly activated—despite insight, effort, and support—it may be worth considering whether the physiology of stress is playing a larger role than expected.
If you’re curious, the next step is a consultation with Dr. Seif to understand your symptoms, review your history, and explore whether this approach fits into your overall plan. You don’t have to force your way into calm. Sometimes, the system needs a different kind of support to find its way there. If you’re ready, contact us to start the conversation.
