Real Relief for Pain That Won't Respond to Anything Else
Stellate Ganglion Block in Denver and Colorado Springs
When pain, persistent symptoms from Long Covid, or a nervous system that won't settle down has stopped responding to conventional treatment, a stellate ganglion block may be the targeted intervention that changes the conversation. At MD Pain, our team of anesthesiologists and interventional pain management specialists offers this precise, image-guided procedure at our Englewood and Colorado Springs locations, with no referral required to get started.
What Is a Stellate Ganglion Block?
A stellate ganglion block is a minimally invasive injection delivered to the stellate ganglion, a collection of sympathetic nerve tissue located in the neck at approximately the level of the sixth cervical vertebra. This cluster of nerves is part of the sympathetic nervous system, which governs the body's fight-or-flight response. When that system becomes overactivated or dysregulated, it can drive a wide range of conditions that feel disconnected from a single structural source of pain.
The procedure involves injecting a local anesthetic, such as bupivacaine, directly into the tissue surrounding the stellate ganglion under fluoroscopic or ultrasound guidance. That guidance is essential. The stellate ganglion sits adjacent to major vascular structures, including the carotid artery and jugular vein, which means imaging is the standard of care. Accurate needle placement allows the anesthetic to interrupt aberrant sympathetic signaling without affecting nearby critical anatomy.
The result is a temporary block of sympathetic nerve activity in that region. For many patients, this interruption allows the nervous system to reset from a state of chronic overactivation. Depending on the indication, effects may begin within hours to days of the procedure, and some patients report that a single block or a short series of blocks produces meaningful, lasting changes in their symptoms.
How the Sympathetic Nervous System Drives Chronic Conditions
The sympathetic nervous system is not just responsible for acute stress responses. In a healthy state, it operates in balance with the parasympathetic system, regulating heart rate, blood flow, inflammation, and the body's overall physiological tone. When this balance is disrupted by trauma, illness, or chronic stress, the sympathetic system can become locked in a state of persistent activation.
This overactivation can manifest as chronic regional pain, hypervigilance, disordered sleep, cognitive fog, and a host of other symptoms that are difficult to address through standard analgesic approaches. The stellate ganglion block works precisely because it interrupts the signaling pathway that is sustaining that dysregulated state, allowing the body's own regulatory mechanisms to reassert themselves.
Conditions We Treat with Stellate Ganglion Block
Post-Traumatic Stress Disorder and Nervous System Dysregulation
One of the most clinically studied emerging applications for stellate ganglion block is in the treatment of PTSD and related trauma-driven nervous system dysregulation. Research published in peer-reviewed journals, including work supported by the United States military, has examined stellate ganglion block as a treatment for veterans and civilians experiencing PTSD symptoms. The proposed mechanism involves reducing elevated levels of nerve growth factor in the stellate ganglion that contribute to sustained sympathetic hyperactivation.
For patients who have not found adequate relief through medication or behavioral therapy alone, or who are specifically seeking a non-narcotic, interventional approach, the stellate ganglion block offers a biological pathway to symptom reduction. At MD Pain, this procedure is delivered with the same precision and individualized planning that defines every treatment we provide.
Long Covid Symptoms and Autonomic Dysfunction
Long Covid has introduced a distinct and growing patient population experiencing symptoms that persist well beyond the acute phase of SARS-CoV-2 infection. These symptoms frequently include fatigue, cognitive dysfunction often described as brain fog, autonomic instability, sleep disruption, and in some cases, chronic pain. Researchers have proposed that dysregulation of the sympathetic nervous system, potentially triggered or amplified by the viral illness itself, may be a contributing mechanism in a meaningful subset of Long Covid cases.
Stellate ganglion block has emerged as a treatment of interest for these patients, with clinical experience suggesting that interrupting aberrant sympathetic signaling may help restore a more balanced autonomic state. Our team monitors the evolving clinical literature on Long Covid carefully and is prepared to discuss whether this procedure is an appropriate option for patients presenting with autonomic or nervous system-driven Long Covid symptoms.
Chronic Regional Pain and Complex Pain Syndromes
Stellate ganglion block has a well-established history in the management of complex regional pain syndrome, particularly in the upper extremities, as well as other sympathetically maintained pain conditions. In these cases, the sympathetic nervous system plays an active role in sustaining pain signals, making conventional analgesic strategies ineffective on their own.
By interrupting the sympathetic contribution to pain, a stellate ganglion block can reduce pain intensity, improve blood flow to the affected area, and in some cases, allow patients to engage more effectively in physical rehabilitation. It is one of several interventional tools the MD Pain team uses to address pain at its root rather than layering treatment approaches that only address surface symptoms.
Hot Flashes and Menopause-Related Vasomotor Symptoms
Clinical evidence has also supported stellate ganglion block as an effective intervention for vasomotor symptoms associated with menopause, particularly hot flashes. For patients who cannot or prefer not to use hormone-based therapies, this offers a non-hormonal, minimally invasive alternative that addresses the sympathetic component of vasomotor dysregulation. The mechanism is consistent with the procedure's broader role in modulating sympathetic nervous system activity.
What to Expect During a Stellate Ganglion Block Procedure
Understanding the procedure from start to finish helps patients arrive prepared and confident. The entire appointment, including preparation, the procedure itself, and a brief post-procedure monitoring period, typically lasts under two hours.
Before the procedure begins, a member of the MD Pain team reviews the patient's medical history, current symptoms, and imaging to confirm that a stellate ganglion block is appropriate and that the planned approach is safe. Patients are positioned on their back with the neck slightly extended to optimize access to the injection site.
The skin is cleaned and a local anesthetic is applied to minimize discomfort at the surface level. Using fluoroscopy or ultrasound guidance, the physician advances a needle to the target position adjacent to the stellate ganglion, typically at the C6 level on the anterior aspect of the cervical spine. A contrast agent may be used to confirm accurate needle placement before the therapeutic agent is injected.
Following the injection, patients remain in a monitored recovery area. It is common to experience temporary changes in sensation on the side of the injection, including a drooping eyelid, redness of the eye, or warmth in the arm. These are expected signs that the block has taken effect and are temporary, resolving within a few hours as the anesthetic clears.
Patients should arrange for a driver on the day of the procedure. Most are able to return to light activities the following day, though the MD Pain team provides individualized post-procedure guidance based on each patient's specific situation.
Imaging Guidance Is Non-Negotiable
Not every facility performs stellate ganglion blocks under real-time imaging guidance. At MD Pain, this is not negotiable. The anterior cervical spine is one of the most anatomically dense regions of the body, with the carotid artery, internal jugular vein, thyroid, esophagus, and spinal cord all in close proximity to the target site. Fluoroscopic or ultrasound-guided placement is the accepted standard for this procedure precisely because it allows the physician to confirm needle position before injection and significantly reduces the risk of inadvertent vascular injection or other complications.
Patients considering this procedure anywhere should ask directly whether imaging guidance is used, because it is a meaningful determinant of both safety and procedural accuracy.

Frequently Asked Questions
A stellate ganglion block is used to address conditions that involve sympathetic nervous system dysregulation. These include complex regional pain syndrome, PTSD and trauma-driven nervous system overactivation, vasomotor symptoms related to menopause such as hot flashes, and emerging applications in Long Covid patients experiencing autonomic dysfunction. At MD Pain, each patient undergoes a thorough evaluation to determine whether this procedure is appropriate for their specific clinical presentation, because not every patient with these conditions is a candidate.
The duration of relief from a stellate ganglion block varies considerably depending on the condition being treated and the individual patient's nervous system. Some patients experience significant symptom improvement that persists for months to years after a single block or a short series of injections. Others may benefit from periodic repeat procedures as part of a longer-term management strategy. The MD Pain team discusses realistic expectations with each patient before the procedure so that treatment decisions are grounded in an honest assessment of likely outcomes.
The procedure involves an injection in the anterior cervical region, which sounds more intimidating than it typically feels. Before the therapeutic injection, the skin and underlying tissue are numbed with a local anesthetic. Most patients report feeling pressure or a mild sensation during needle placement, but not significant pain. The use of imaging guidance at MD Pain allows our physicians to place the needle accurately on the first pass, which minimizes both the time of the procedure and any associated discomfort. Post-procedure soreness at the injection site is common and typically resolves within one to two days.
No referral is required. MD Pain accepts new patients with and without a physician referral. If you have been managing a condition that you believe may respond to stellate ganglion block therapy, or if another provider has suggested this procedure and you are looking for a specialist to perform it, you can contact our team directly to schedule a consultation. Our Englewood and Colorado Springs locations both accept new patients, and the evaluation process begins with a thorough review of your history and symptoms.
Like any interventional procedure, stellate ganglion block carries potential risks that patients should understand before proceeding. The most commonly discussed temporary effects include Horner's syndrome signs on the injected side, specifically drooping of the eyelid, redness or bloodshot appearance of the eye, and warmth in the arm. These are expected physiological responses to the sympathetic block and resolve within a few hours. More serious risks, including vascular injection or injury to nearby structures, are significantly reduced when the procedure is performed under real-time imaging guidance, which is the standard at MD Pain. A thorough pre-procedure consultation gives each patient a clear picture of the specific risks and benefits relevant to their situation.
The number of injections needed depends entirely on the condition being treated and how the patient responds to the initial procedure. Some patients achieve meaningful, lasting relief from a single block. Others benefit from a series of two to three injections spaced several weeks apart, allowing the nervous system time to stabilize between treatments. MD Pain does not follow a one-size-fits-all protocol. The team evaluates each patient's response after the first procedure and makes recommendations based on what the clinical picture shows.
Stellate ganglion block is an area of active clinical interest for Long Covid patients experiencing autonomic nervous system dysfunction. These patients often present with fatigue, brain fog, heart rate irregularities, and other symptoms that are difficult to address through conventional approaches. The theory is that viral illness may trigger or amplify sympathetic dysregulation in susceptible individuals, and that interrupting that sympathetic overactivation through a precisely delivered block may help restore autonomic balance. MD Pain monitors the evolving evidence on this application carefully, and our team is prepared to have an honest conversation with Long Covid patients about whether this procedure may be appropriate for their specific symptom profile.
