A vagus nerve block is a procedure used to manage chronic pain and certain neurological conditions by targeting the vagus nerve, crucial for pain modulation, inflammation, and autonomic nervous system function. It is explored for conditions like chronic migraines, inflammatory disorders, gastrointestinal pain, and some neuropathic pain types.

During the procedure, a small needle is guided near the vagus nerve, usually in the neck, using ultrasound for precision. A local anesthetic, sometimes with a steroid, is injected to temporarily block nerve signals, reducing pain and autonomic dysfunction. Effects may last weeks to months, with possible repeated treatments for long-term relief.

This procedure may assist with: - Chronic headaches and migraines - Neuropathic pain conditions, such as fibromyalgia or complex regional pain syndrome (CRPS) - Inflammatory disorders involving autonomic nervous system - Gastroparesis and functional abdominal pain

If effective, further treatments like radiofrequency ablation (RFA) might offer longer-lasting relief.

Alternative treatments include: - Medications like anti-inflammatory drugs - Vagus nerve stimulation (VNS), delivering electrical pulses for chronic conditions - Physical therapy and lifestyle changes

If nerve blocks and RFA don't provide lasting relief, advanced treatments like peripheral nerve stimulation (PNS) or Spinal Cord Stimulation (SCS) may be considered.

While generally safe, risks include temporary hoarseness, mild throat discomfort, dizziness, or, rarely, nerve irritation or infection. Your provider may advise pausing certain medications like blood thinners, but this isn't always needed.

You may be asked to fast if sedation is used, though most are done under local anesthesia. Afterward, rest and avoid strenuous activity for a day, with a follow-up to assess response and next steps.

If chronic pain or autonomic dysfunction affects your life, a vagus nerve block may help.
