Cervical sympathetic blocks (Stellate Ganglion blocks) and Lumbar sympathetic blocks relieve pain originating in the sympathetic nervous system. The sympathetic nervous system is a separate system that is responsible for pain, skin color, temperature, light touch, and hair growth. When pain originating from the sympathetic nervous system is suspected, these fibers can be blocked in the neck or the low back. These procedures are designed to treat symptoms of Complex Regional Pain Syndrome or Causalgia (CRPS).

A local anesthetic is utilized for the injection. The patient may feel warmth or experience a temperature change in the affected arm or leg. This is a sign that the sympathetic fibers have been blocked. Even though this reaction is temporary, pain relief can persist and the abnormality of the sympathetic nervous system can be reversed. To achieve more permanent relief, repeated injections are typically needed, along with supportive physical therapy.

Side effects of Sympathetic Blocks are rare and your provider will discuss them with you. You will be asked to sign a written consent prior to the procedure, as well as a brief medical history questionnaire. You will also be asked to refrain from taking any NSAIDs or other blood-thinning medications within three days of the procedure, to prevent increased bruising.

Sympathetic Blocks, as with most other procedures, are performed in our fluoroscopy suite. X-ray, or fluoroscopy, is used for nearly all injections to ensure safety and accuracy. Intravenous sedation is offered. If you receive any anesthesia, you will not be able to drive following your procedure, so please make arrangements for transportation. You may resume normal activities the day after the procedure, unless otherwise directed by your physician. It may take several days to feel the full effects of the procedure. Your provider will schedule a follow-up evaluation to evaluate the results of the procedure.

Sympathetic blocks can produce dramatic results in a patient suffering from an abnormality of the sympathetic nervous system. Please contact our office if you have additional questions regarding this procedure.
