Lumbar Sympathetic Block Treatment
Lumbar sympathetic block injections, commonly referred to as LSB injections, are a minimally invasive procedure that can effectively alleviate chronic pain in your lower back and legs by targeting the sympathetic nerves in the lumbar region. These nerves play a crucial role in controlling various functions in your body. The medication from the injection works to block pain signals from these nerves and prevents them from reaching the brain. As a result, you experience significant relief, allowing you to regain control over your life and return to your daily activities with renewed functionality.

Dr. Rao. I can't find the words to tell you how much he has meant to me. I followed him from an old practice to his very new high tech office. They offer so many different areas of assistance to those with issues from nutrition to spinal surgery... and much more. His office is professional.

What Is a Lumbar Sympathetic Block?
A sympathetic nerve block injection is a minimally invasive and safe procedure that can provide immediate and long-term relief in the body's lower extremities.
The lumbar sympathetic nerve block procedure involves injecting a medication containing steroids and a local anesthetic directly into the lumbar sympathetic nerves located on both sides of the spine in the lower back. The injection works by blocking the transmission of pain signals from the lumbar nerves to the brain, providing both diagnostic and therapeutic benefits.
These injections offer a safe and effective alternative to conventional surgeries and medications, ensuring a more comprehensive and holistic approach to pain management. With their proven track record, LSB injections have emerged as a valuable treatment option that not only addresses the symptoms but also addresses the underlying causes of chronic pain, facilitating long-lasting relief and improved quality of life.
Diagnostic and Therapeutic Results
When the lumbar block is delivered to the branch of nerves suspected of causing spinal block pain, it can produce diagnostic or therapeutic results. The diagnostic result occurs when a patient experiences relief right after the injection, which can help pinpoint the source of their pain. The therapeutic results occur when the injection reduces or even eliminates the patient's pain for an extended period of time. Your doctor may recommend a series of injections for long-term relief.
What Is Sympathetic Nerve Activity?
The sympathetic nervous system (SNS) is part of the autonomic nervous system (ANS). The autonomic nervous system is comprised of both the sympathetic and parasympathetic nervous systems and works to regulate different functions in the body.
The sympathetic nerves run parallel to the spinal cord on both sides of the vertebral column. The sympathetic nerves respond to stress and increase the stress hormone known as cortisol and trigger the fight-or-flight response in the body. They also aid in involuntary bodily functions such as digestion, sweating, and blood flow. The sympathetic nerves start near the middle of the spinal cord and extend down into the second or third lumbar vertebrae.
The sympathetic block is performed on the side of the body where the pain exists, and the medication is injected into the sympathetic ganglia by the spine.

The Lumbar Sympathetic Block Procedure
Knowing what to expect in a lumbar nerve block procedure is essential to ensuring a successful and comfortable experience. Here is a detailed overview of preparation steps, procedure technique, what you should expect after treatment:


Preparing for the Procedure
Before the procedure, our doctors all patients with detailed instructions to follow. These might include dietary recommendations, such as fasting for a certain period, or adjustments to current medication regimen. It's crucial to adhere to these instructions to ensure the procedure goes smoothly.
The Procedure
On the day of the procedure, patients are placed on an x-ray table, lying on their stomach. The area where the needle will be inserted is numbed with a local anesthetic. Using fluoroscopy, a form of X-ray, the doctor guides a thin needle towards the lumbar sympathetic nerves situated on either side of the lower spine. Once the needle is correctly positioned, an anesthetic medication is injected to block nerve signals. Typically, the procedure takes about 30 minutes.
Patients should not experience any significant pain during the procedure. They might feel a slight sting from the initial injection of the local anesthetic and some pressure when the needle is inserted.
Directly After the Procedure
Right after the procedure, patients may feel a warm sensation in their legs and feet. This is generally a positive indication that the Lumbar Sympathetic Block has been successful.
Patients are advised to arrange transportation home as the anesthetic can impair their ability to drive safely. Post-procedure, they are monitored for a short period to ensure there are no immediate complications.
Pain relief can be experienced shortly after the procedure and can last several hours or even days. Some patients may need a series of injections to achieve optimal pain relief.
Long Term Recovery and Results After a Sympathetic Nerve Block
Since this is an outpatient treatment, most patients are fully back to performing daily activities the next day. We do advise patients not to swim or soak in a tub for 72 hours. Any soreness can usually be relieved using an ice pack or an over-the-counter pain reliever (be sure to consult with your doctor first). If numbness hasn't gone away after 24 hours or there is a loss of bladder or bowel control, the patient needs immediate medical attention.
Patients may not feel the effects of the lumbar block until a few days later, and how long they find relief from their pain varies, depending on the person. Some may see relief for weeks, and some may see relief for months. A couple more injections may be needed throughout the year but should be limited due to potential risks. Patients may also benefit from physical therapy with the sympathetic nerve block to relieve pain.
What Are the Risks of Lumbar Blocks?
Overall risks for lumbar sympathetic nerve blocks are relatively low, but not completely zero. This is a minor treatment that is non-invasive, so the chances of having a serious complication are not very likely. However, the patient should keep an eye out for signs of infection or bleeding. Infections are one of the more concerning outcomes of this procedure, but can be treated easily with an antibiotic. There are also chances of an allergic reaction to the medication or nerve damage occurring. Generally, the patient can expect some potential bruising or soreness at the injection site for a few days.
