Sympathetic Ganglion Blocks

 Advanced image-guided nerve blocks that target the body’s sympathetic nervous system to relieve chronic pain and restore function.

What Are Sympathetic Ganglion Blocks?

Sympathetic Ganglion Blocks are precise injections that target clusters of nerves within the sympathetic nervous system — the network controlling pain signals, blood flow, and other automatic body responses.
When these nerves become overactive due to injury, surgery, or disease, they can cause severe, persistent pain, swelling, or vascular problems.
 By temporarily blocking these nerves, the procedure helps reduce pain, improve circulation, and restore normal nerve balance.

When Are They Used?

Sympathetic blocks are typically recommended for:

Complex Regional Pain Syndrome

of the arm or leg

Facial or Head Pain

(e.g., trigeminal neuralgia, cluster headaches)

Vascular-Related Pain

(e.g., poor circulation or Raynaud’s disease)

Cancer Pain

in the neck, chest, or pelvis

Post-Surgical / Phantom Limb Pain

Post-Surgical or Phantom Limb Pain

How It Works

Benefits

Fast, targeted pain relief

Improved blood flow and temperature regulation in affected limbs

May reverse abnormal nerve activity causing chronic pain

Can reduce swelling and hypersensitivity

Outpatient procedure with minimal recovery time

Serious risks are rare but include infection, bleeding, or nerve damage.

What to Expect

Procedure

Performed under X-ray or ultrasound guidance; a small amount of anesthetic (and sometimes steroid) is injected precisely around the ganglion.

Follow-up

Depending on response, repeat blocks or advanced options like Radiofrequency Ablation may be recommended for longer-lasting results.

Consultation & Imaging

Dr. Babak identifies the overactive nerve region using clinical evaluation and diagnostic imaging.

Recovery

Temporary side effects are expected (e.g., drooping eyelid, hoarseness, or stuffy nose for an SGB ). Pain relief may begin in hours.
