At the base of your neck, where your neck meets your collarbone, sits a small but critical nerve cluster called the stellate ganglion. Think of it as the primary relay station for your sympathetic nervous system in your upper body — governing the stress response throughout your head, face, neck, arms, and chest.
When it’s functioning well, it helps your body shift fluidly between alert and at ease as situations demand. When it’s overactive — stuck in the “on” position from chronic stress, trauma, prolonged anxiety, or repeated illness — it keeps your upper body locked in a state of constant alert: shoulders braced, jaw clenched, mind racing, sleep disrupted, even when there’s nothing left to protect against.
Like a smoke detector that won’t stop going off after the fire is out, the signal keeps firing regardless of what you do to try to calm it.
The conventional approach to an overactive stellate ganglion is a nerve block — a local anesthetic that temporarily quiets the signal. The Stellate Ganglion Reset takes a different approach.
Rather than muting the signal, RenuO2 therapy is delivered directly to the nerve center to help reset it. RenuO2 calms the overactive sympathetic nerve fibers, reduces inflammation around the nerve tissue, improves local circulation, stabilizes nerve cell membranes so they stop firing unnecessarily, and supports the environment nerve tissue needs to heal and rebalance.
The goal isn’t temporary suppression. It’s helping the nerve center return to balanced, appropriate signaling — addressing why the alarm is going off, not just quieting it for a while.
The procedure takes less than 30 minutes. You lie comfortably while your provider uses anatomical landmarks to precisely locate the stellate ganglion and delivers RenuO2 via a fine needle. Most patients experience minimal discomfort.
Within minutes, many patients notice a warmth spreading through the arm and hand on the treated side — a sign the treatment is working — along with a subtle release of tension they hadn’t fully recognized they were holding, and a quieting of the background noise that had become so constant it felt normal.
Most protocols involve a series of treatments spaced over several weeks, with each session building on the previous one. Some patients notice meaningful change after a single session.
The Stellate Ganglion Reset has shown particularly strong results for chronic stress and anxiety, PTSD and trauma-related conditions, panic and performance anxiety, treatment-resistant anxiety, chronic tension headaches and migraines, TMJ and jaw tension, brain fog and difficulty concentrating, sleep disturbances related to an overactive mind, hot flashes related to hormonal changes, and difficulty transitioning out of a state of stress or vigilance.
Military research has documented significant improvement in PTSD symptoms in the majority of patients treated with stellate ganglion therapy — making it one of the more rigorously studied interventions for treatment-resistant stress conditions.
The Stellate Ganglion Reset is generally well-tolerated. It is not appropriate for patients with active infection at or near the injection site, allergy to RenuO2 components, or significant bleeding disorders. Side effects are typically mild — temporary soreness at the injection site, brief lightheadedness, or transient warmth in the treated arm. Your provider will review your history and determine whether this therapy is appropriate during your Discovery evaluation.
