The Science Behind Sympathetic Nerve Blocks Explained

• Definition: A sympathetic nerve block is an injection of anesthetic medicine into the region where the sympathetic nerve chain is located. This chain extends along the front side of the spinal column and is not involved with movement or sensation but rather with the 'fight or flight' response in the body.
• How it works: By introducing local anesthetics to the sympathetic nerves, these blocks can disrupt pain signals sent by these nerves, providing relief and aiding in the diagnosis of pain syndromes related to the sympathetic nervous system.

• Prior to the procedure, your medical history will be reviewed, and necessary imaging or tests may be done.
• The patient is positioned comfortably, and the skin over the injection site is cleaned and numbed.
• Using fluoroscopic or ultrasound guidance, the physician will carefully introduce the needle to the targeted site and deliver the medication.
• The procedure usually takes between 15 to 30 minutes.
• Post-procedure, patients might experience temporary numbness or weakness. It's advised to have someone accompany the patient home.
• The relief duration varies; some may experience weeks of relief, while others could benefit for months. The treatment can be repeated if necessary.
