Sympathetic ganglion blocks are collectively medical procedures used to block the pain from deep organs such as the stomach or pelvis.
Our body has a system called the sympathetic nervous system that helps control things like heart rate, blood pressure, and pain. Sometimes, this system can cause pain to get worse, especially in long-term conditions. Think of pain from sympathetic system as a separate pain from the regular pain when, for example, a needle pokes you in your finger. Doctors can perform something called a “Sympathetic Nerve Block” to help relieve this kind of pain. This is a special shot given near certain nerves to stop pain signals from traveling to the brain.
At Cherry Medical, we understand that chronic pain can deeply affect your quality of life. Under the care of Dr. Alireza Bozorgi, a triple board‑certified neurologist and pain specialist, we offer advanced treatments such as Sympathetic Ganglion Block to help control and reduce pain that originates from the sympathetic nervous system.
For pain relief with Sympathetic Ganglion Block, call Cherry Medical at (714) 819-0000 today.
Doctors at Cherry Medical recommend a sympathetic block for various pain conditions where overactive sympathetic nerves are involved, including:
Main Categories of Pain:
Chronic and Condition‑Specific Pain Examples:
The sympathetic nervous system runs along your spine and connects to organs through special nerve paths. Doctors use live X-Ray (fluoroscopy) or ultrasound to carefully guide a needle to the right spot near these nerves. They inject medication that stops pain signals. Sometimes, they use medicine that works for a short time (to see if it helps), and other times, they use longer-lasting medicine or even heat to destroy the nerve for long-term relief.
Each type is tailored to a specific anatomic region and pain source.
Sympathetic nerve blocks are used to diagnose and treat a wide range of chronic pain and autonomic conditions, including:
Cherry Medical’s treatment Services are designed to help improve your well-being and quality of life.
| Type of Pain Treated | Benefits of Sympathetic Ganglion Block | Risks & Side Effects of Sympathetic Ganglion Block |
|---|---|---|
| Visceral Pain (pain from internal organs: stomach, pancreas, intestines) | Significant reduction in internal organ pain; improvement of digestive and abdominal function | Mild soreness at injection site, transient low blood pressure, or mild nausea |
| Neuropathic Pain (nerve injury‑related pain) | Decreases burning and tingling sensations; restores nerve‑signal balance | Temporary numbness or weakness; rare nerve irritation |
| Ischemic / Vascular Pain (caused by poor blood flow) | Improves circulation and oxygenation; warms cold limbs; supports tissue healing | Temporary hypotension, dizziness, or localized warmth |
| Sympathetically Mediated Pain / CRPS | Calms overactive sympathetic nerves; reduces chronic limb pain, swelling, and stiffness | Vasovagal reaction (faintness or nausea); mild bruising at injection site |
| Chronic Pelvic Pain | Relieves deep pelvic or genital pain; enhances mobility and sexual comfort | Temporary pelvic pressure or numbness |
| Phantom Limb Pain | Reduces perception of pain in amputated limbs by resetting central nerve pathways | Brief light‑headedness or flushing |
| Abdominal / Pancreatic Pain | Relieves pain from pancreatitis or abdominal cancers; improves appetite and comfort | Mild nausea, transient weakness, or drop in blood pressure |
| PTSD ‑ Related Autonomic Pain (treated with stellate ganglion block) | Improves focus, sleep, and emotional regulation; decreases stress response via sympathetic modulation | Temporary hoarseness, dry throat, or mild sensation of warmth |
People with allergies to the medicines used, those with active infections, or who are on certain blood thinners might not be good candidates. The best candidates are patients whose pain appears to be sympathetically mediated. Those with uncontrolled infections, bleeding disorders, or medication allergies may require special evaluation first. During your consultation, Dr. Bozorgi will review your medical history and imaging results to determine the best approach.
You may remain in our clinic for 30–60 minutes for observation. Some patients feel immediate relief, while others may notice improvement in the following days. You can usually return to normal activities within 24 hours. For chronic pain cases, a series of sympathetic ganglion block treatments may be recommended for sustained results. At Cherry Medical, every treatment begins with understanding you — your story, your pain, your goals — and ends with a personalized plan to help you live pain‑free again.

By numbing the sympathetic ganglia, it interrupts nerve signals that transmit pain to the brain.
Alternatives or repeat injections may be recommended; your doctor will explore other treatment options for managing the condition.
No, it may also help some mental health conditions like anxiety, depression, and PTSD, although these uses are generally off-label.
Common types include Stellate Ganglion Block (neck), Lumbar Sympathetic Block (lower back), and others targeting specific regions for circulation or pain issues.
Relief can last from hours to months; repeat treatments are possible if needed.
Stellate ganglion blocks target nerves in the neck for upper body pain, while lumbar blocks target lower back nerves for leg and lower body pain.
Yes, lumbar sympathetic blocks are used for CRPS affecting the foot, and stellate blocks may be used for CRPS in the hand or upper limbs.
Yes, with low risk when performed by an experienced physician. Possible side effects include injection site soreness, slight bleeding, temporary numbness, or rare nerve damage.
Sympathetic ganglion block refers to blocking any sympathetic nerve ganglion to reduce pain. Stellate ganglion block targets the stellate ganglion in the neck, mainly for pain in the head, neck, chest, and arm.
