Sympathetic Nerve Block
Procedures
Minimally Invasive Pain Relief
A sympathetic nerve block is a minimally invasive injection used to diagnose and relieve chronic pain linked to the sympathetic nervous system. Holistiq Spine & Orthopaedic offers this advanced pain management procedure along with holistic care to help patients maximize long-term wellness and mobility.
What Is a Sympathetic Nerve Block?
A sympathetic nerve block involves injecting anesthetic medication near sympathetic nerves that run along the spine. These nerves control involuntary body functions, such as blood flow and sweating, and may become sources of persistent pain. By selectively numbing them, the block can pinpoint the pain’s source and provide significant, sometimes long-lasting pain relief.
Conditions Treated
Sympathetic nerve blocks are used for:
- Complex regional pain syndrome (CRPS/RSD)
- Neuropathic pain, especially in arms, legs, hands, and feet
- Vascular pain (poor circulation, Raynaud’s syndrome)
- Visceral pain from abdominal or pelvic organs
- Pain after shingles (herpes zoster and postherpetic neuralgia)
- Phantom limb pain after amputation
- Scleroderma, frostbite, or other sympathetic dysfunctions
- The procedure can also help in diagnosing whether the sympathetic nervous system is causing pain.
Potential Candidates for the Procedure
Candidates typically:
- Have chronic pain diagnosed as sympathetically mediated after thorough evaluation and imaging
- Suffer from moderate to severe pain unresponsive to conventional therapies (physical therapy, medications, counseling)
- Do not have active infection, medication allergies, or major psychological barriers
- May benefit most if treated early in the course of their pain syndrome
Research
- A major study showed over 60% of CRPS patients experienced more than 50% pain relief after sympathetic blocks; pain relief lasted one to four weeks or longer in most cases. Early intervention leads to better outcomes.
- Sympathetic nerve blocks have emerging evidence in treatment-resistant PTSD, with most patients experiencing mild and transient side effects. More standardized clinical trials are needed.
- Repeated nerve blocks may lead to cumulative, longer-lasting pain benefits in selected patients.
What to Expect
Before, During and After the Procedure
Before: An initial evaluation will confirm the diagnosis and decide block level (cervical, lumbar, or pelvic). Medications may be adjusted and fasting required prior to the procedure.
During: The patient lies comfortably as a small needle, guided by x-ray or ultrasound, injects local anesthetic near the spine. Sedation may be given for comfort. The process takes about 30 minutes.
After: Brief observation follows—most patients return home the same day. Temporary numbness, warmth, or weakness is common, with pain relief often developing quickly. A series of injections may be recommended for best results.
Expected Outcomes
- Marked pain relief in the majority of appropriately selected patients (50% relief or more in most studies)
- Improved mobility, function, and quality of life
- Reduced need for opioid pain medications
- Minimal downtime and rapid return to normal activities
Alternative Treatments
- Medications: Anticonvulsants, antidepressants, non-opioid analgesics
- Physical & occupational therapy for movement restoration
- Psychological therapies such as cognitive-behavioral therapy
- Nerve ablation, spinal cord stimulation, or surgical sympathectomy in refractory cases
- Holistic options: nutrition planning, acupuncture, mind-body techniques

FAQs About Spinal Cord Stimulators
How quickly does a sympathetic nerve block work?
Pain relief is often felt within hours, but may take up to a few days. Effects can last weeks or longer.
How many blocks will I need?
Most patients require a series of two to six blocks (sometimes more) for optimal results, spaced over several weeks.
What are the risks and side effects?
Risks are low and include temporary soreness, infection, bleeding, or short-term numbness or weakness. Rare side effects depend on injection site (e.g., hoarseness or swallowing difficulty after cervically placed blocks).
Will the block “cure” my pain?
The block may provide lasting or repeated relief but does not cure the underlying cause for most patients. It can be diagnostic and therapeutic.
Can I return to normal activities after the procedure?
Yes—most people resume daily activities within a day, but should arrange a driver after sedation.
Why Choose Holistiq Spine & Orthopaedic?
