Understanding Sympathetic Nerve Blocks

Chronic pain can be debilitating, affecting every aspect of daily life and diminishing overall quality of life. For those suffering from chronic pain conditions, finding effective relief can be a challenging journey. Fortunately, interventional pain management techniques offer hope for individuals seeking long-term relief from persistent pain.   One such technique is the sympathetic nerve block, a procedure that can provide significant relief for certain types of chronic pain.

​

What are Sympathetic Nerves?

The sympathetic nervous system is responsible for regulating involuntary bodily functions, including the body's response to stress and pain. When this system becomes overactive or dysfunctional, it can contribute to chronic pain conditions such as complex regional pain syndrome (CRPS), neuropathic pain, and certain types of visceral pain.

​

What are Sympathetic Nerve Blocks?Sympathetic nerve blocks are minimally invasive procedures designed to target and interrupt pain signals transmitted by the sympathetic nervous system. During a sympathetic nerve block, a local anesthetic or medication is injected near the sympathetic nerves responsible for transmitting pain signals from the affected area to the brain. By temporarily blocking these nerves, the procedure can provide immediate pain relief and help break the cycle of chronic pain.

​

Conditions Treated with Sympathetic Nerve Blocks:Sympathetic nerve blocks are commonly used to manage various chronic pain conditions, including:

• Complex Regional Pain Syndrome (CRPS):  CRPS is a chronic pain condition characterized by intense burning pain, swelling, and changes in skin color and temperature. Sympathetic nerve blocks can help alleviate pain and improve function in individuals with CRPS.

• Neuropathic Pain:  Neuropathic pain arises from damage or dysfunction of the nerves and is often described as shooting, burning, or stabbing pain. Sympathetic nerve blocks can be effective in treating neuropathic pain conditions such as peripheral neuropathy and postherpetic neuralgia.

• Visceral Pain: Visceral pain originates from the internal organs and can be challenging to treat with traditional pain medications. Sympathetic nerve blocks can provide relief for visceral pain conditions such as pancreatic pain and pelvic pain syndromes.

 

Procedure:

Sympathetic nerve blocks are performed as outpatient procedures in our clinic. The procedure is guided by fluoroscopy(X-ray) imaging to ensure precision and accuracy.

• Preparation: Before the procedure, the patient will be positioned comfortably on an examination table, and vital signs will be monitored.

• Anesthesia: The skin over the injection site will be cleaned and numbed with a local anesthetic to minimize discomfort during the procedure.

• Injection: Using fluoroscopy, a thin needle will be inserted near the targeted sympathetic nerves. A mixture of local anesthetic and anti-inflammatory medication, such as corticosteroids, may be injected to provide both immediate and long-lasting pain relief.

• Post-Procedure Care: After the injection, patients are typically monitored for a brief period to ensure there are no immediate complications. Some patients may experience temporary numbness or weakness in the affected area, but this usually resolves quickly.

 

Benefits of Sympathetic Nerve Blocks:Sympathetic nerve blocks offer several benefits for individuals struggling with chronic pain, including:

• Targeted Pain Relief: By directly targeting the sympathetic nerves responsible for transmitting pain signals, nerve blocks can provide targeted pain relief with minimal systemic side effects.

• Improved Function:Pain relief from sympathetic nerve blocks can help individuals regain mobility and function, allowing them to participate in daily activities and physical therapy more effectively.

• Reduced Need for Medications: For individuals who have not found relief with medications or prefer to avoid long-term medication use, nerve blocks offer an alternative approach to pain management.

​

Sympathetic nerve blocks are valuable tools in the arsenal of interventional pain management techniques. By targeting the underlying mechanisms of chronic pain, these procedures can provide significant relief for individuals suffering from a wide range of conditions. If you're struggling with chronic pain that has not responded to conservative treatments, talk to a pain management specialist to see if sympathetic nerve blocks could be a suitable option for you. With the right treatment approach, you can take steps toward reclaiming your life from chronic pain.
