Short and Long-Term Side Effects of Stellate Ganglion Block

stellate ganglion block side effects

The rapid advancements in medical science and technology over the past century have revolutionized the treatment of numerous disorders and diseases once deemed untreatable. Addiction treatment has undergone significant transformation as well.

In the past, individuals with alcohol addiction were often confined to asylums, and Sigmund Freud even suggested cocaine as a treatment for alcoholism. Today, addiction is recognized as a disease that requires compassionate and respectful care, focusing on the person rather than just the symptoms. However, the increasing complexity of treatments naturally raises concerns about potential side effects.

One of the newest and most promising treatments for addiction is the stellate ganglion block. If you’re exploring stellate ganglion block options in Massachusetts, the team at Rockland Recovery is here to address your concerns and provide comprehensive information. Reach out to our knowledgeable admissions staff to learn more about this innovative procedure.

What Is Treated With Stellate Ganglion Blocks?

A stellate ganglion block (SGB) is both a therapeutic and diagnostic procedure that can offer significant relief from pain and other symptoms. This procedure involves injecting a local anesthetic around the stellate ganglion, a collection of sympathetic nerves located in the neck.

By blocking these nerves, the SGB can interrupt signals and provide relief from a variety of conditions and disorders, including:

  • Complex Regional Pain Syndrome (CRPS): Also known as reflex sympathetic dystrophy, CRPS is a chronic pain condition often treated effectively with stellate ganglion blocks.
  • Nerve Injuries: SGB can help alleviate pain resulting from nerve damage and injuries.
  • Shingles: The severe pain associated with shingles, a viral infection, can be relieved through this treatment.
  • Scleroderma: This autoimmune disease, which causes hardening and tightening of the skin, can benefit from SGB.
  • Hyperhidrosis: Excessive sweating, or hyperhidrosis, can be managed with stellate ganglion blocks.
  • Phantom Limb Pain: Individuals experiencing pain in a limb that has been amputated can find relief through SGB.
  • Anxiety Disorders such as PTSD: SGB has shown promise in treating the symptoms of post-traumatic stress disorder.
  • Addiction: Emerging research suggests that stellate ganglion blocks can help in the treatment of addiction.

Many patients report near-instantaneous relief from their symptoms, with others experiencing at least partial relief in the days and weeks following the treatment. Stellate ganglion blocks are particularly effective for those who have tried other treatment options without adequate results.

SGB for Pain Relief

Stellate ganglion blocks are a powerful tool in pain medicine, providing relief from intense pain associated with various conditions. The procedure involves a sympathetic nerve block, which targets the nerves to interrupt signals and treat pain effectively. This method is especially beneficial for long-term pain management in patients who have not found relief through other treatments.

While SGB is generally safe, it is important to be aware of potential serious complications, such as infection or nerve damage. However, the benefits of relieving pain and improving quality of life often outweigh the possible dangers for most patients.

How Stellate Ganglion Nerve Block Works

A stellate ganglion block is a type of injection that stops the nerves’ signals in the neck at the sides of the voice box. This collection is known as the stellate ganglion, and the procedure is so named because the end goal is to block these nerves from overloading the brain with the signals that trigger the fight-or-flight response. The stellate ganglion is responsible for the functioning of the sympathetic nervous system, which causes many of the effects of anxiety and addiction. A stellate ganglion block can allow the brain to reset and recover when the sympathetic nervous system is malfunctioning or overly active for a long period.

Many studies have found positive results when stellate ganglion block is used to treat anxiety disorders such as PTSD and substance use disorders rooted in anxiety. The treatment is also fast, taking around 15 minutes to be administered by a medical professional. Understandably, some people may be wary of injections to the neck. However, stellate ganglion block is a relatively safe and simple procedure that involves little pain for the client being treated.

Short-Term Side Effects of Stellate Ganglion Block

Patients undergoing a stellate ganglion block may experience several short-term side effects. Commonly reported symptoms include numbness in the neck, upper chest, or upper arm, which typically resolves within a few hours. Some patients might also notice a stuffy nose and minor discomfort at the injection site.

Changes in vital signs, such as fluctuations in blood pressure, can occur as the local anesthetic affects the sympathetic nerves. Although these side effects are generally mild and temporary, it’s important to monitor for any adverse reactions following the treatment.

Long-Term Side Effects of Stellate Ganglion Block

While stellate ganglion blocks are considered safe, there are potential long-term risks to be aware of. Rarely, patients might experience prolonged circulation problems due to nerve or blood vessel damage.

Chronic issues such as high blood pressure or ongoing changes in heart rate may also arise, although these are uncommon. Long-term complications are typically minimal when the procedure is performed by an experienced practitioner, but patients should always discuss potential risks with their healthcare provider before undergoing the treatment.

The Procedure and What to Expect

A stellate ganglion block involves using a thin needle to inject anesthetic medication near the collection of nerves in the neck. The doctor will use imaging guidance to ensure accurate needle placement and avoid any complications. During the procedure, which typically takes around 15 minutes, patients may feel minor discomfort at the injection site. The goal is to block the nerves from sending pain signals, providing significant pain relief. After the injection, patients are usually monitored in a recovery room for a short period before being allowed to go home the same day.
