Stellate Ganglion Block

The stellate ganglion is a collection of nerves located in the neck, part of the sympathetic nervous system, which transmits pain signals from the head, neck, chest, and upper limbs. A Stellate Ganglion Block (SGB) is a minimally invasive procedure where local anesthetic is injected around these nerves to block abnormal pain signals and improve blood flow. This procedure is particularly useful in treating chronic pain syndromes, nerve-related pain, and certain vascular or circulation issues in the upper body. It can significantly reduce pain, improve mobility, and enhance quality of life.

Signs & Symptoms Where a Stellate Ganglion Block May Help

 

You may be a candidate for this procedure if you have:

  • Chronic pain in the face, head, neck, chest, or upper limbs

  • Complex Regional Pain Syndrome (CRPS) affecting the arm or hand

  • Post-herpetic neuralgia (shingles pain) in the upper body

  • Vascular insufficiency leading to cold or painful hands/arms

  • Pain following certain injuries or surgeries in the upper body

  • Excessive sweating of the face, head, or upper limbs (hyperhidrosis)

Diagnostic Procedure

 

Before recommending a Stellate Ganglion Block, Dr. Manish De follows a detailed diagnostic pathway to ensure patient safety and effectiveness:

  • Comprehensive Medical History & Examination – To identify the cause and distribution of pain.

  • Imaging Studies – X-ray, CT scan, or MRI may be advised to rule out structural causes of pain.

  • Test Block – A small amount of anesthetic may be given first to assess patient response before performing a long-acting block.

  • Fluoroscopic or Ultrasound Guidance – Used to place the needle with precision, ensuring safe and accurate medication delivery.
