Ganglion Block
Ganglion blocks are specialized procedures that target the sympathetic nervous system to help manage chronic pain and certain nerve-related conditions. By injecting medication around specific sympathetic ganglia, these blocks interrupt pain signals and reduce abnormal nerve activity that may contribute to persistent pain, inflammation, or hypersensitivity.
Originally developed over a century ago for pain relief, ganglion blocks are now commonly used to treat conditions such as Complex Regional Pain Syndrome (CRPS), postherpetic neuralgia, hyperhidrosis, and other chronic pain disorders. In some cases, the benefits may last longer than the medication itself by helping calm overactive pain pathways and reducing nervous system hyperexcitability. These procedures can also support improved function, comfort, and quality of life as part of a comprehensive pain management plan.

Before a ganglion block, the provider will review your medical history, symptoms, medications, allergies, and previous treatments. Imaging studies and a physical examination may be performed to identify the appropriate sympathetic ganglion to target. Patients may receive instructions regarding fasting, medication adjustments, or arranging transportation after the procedure. The treatment plan will be discussed to ensure the procedure is safe and appropriate for your condition.
|
During a ganglion block, the patient is positioned comfortably while the treatment area is cleaned and prepared using sterile technique. Using imaging guidance such as fluoroscopy or ultrasound, the provider carefully places a needle near the targeted sympathetic ganglion and injects medication to interrupt abnormal pain signaling and nerve activity. The procedure is typically brief and designed to provide targeted relief while minimizing discomfort. Patients are usually awake throughout the treatment, although mild sedation may sometimes be provided for comfort.

After the procedure, patients are monitored for a short recovery period to assess their response and ensure stability. Temporary numbness, warmth, weakness, or mild soreness near the injection site may occur and generally resolves within a short time. Many patients notice reduced pain, improved circulation, or increased comfort following treatment. Providers may recommend activity modifications, physical therapy, or follow-up care depending on the condition being treated. The duration of relief varies from patient to patient and may improve with a series of treatments as part of a comprehensive pain management plan. |
