During a Dual Sympathetic Block procedure your doctor injects a local anesthetic into your Stellate Ganglion nerve cluster (on the side of your neck). The anesthetic immediately numbs the nerve cluster and resets the sympathetic nervous system.
The process is typically completed in under 15 minutes. After the injection your doctor will monitor your body’s initial response to the block.

Common Conditions
What are the Benefits?​
Dual Sympathetic Blocks are efficient outpatient procedures that don't require any major incisions or significant downtime.
 By resetting the nervous system's heightened state, DSBs can help to alleviate pain and reduce inflammation.
Blocking signals along the sympathetic nervous system may reduce constriction of blood vessels.
DSBs reset the nervous system's heightened fight-or-flight state, giving the body a break from anxiety, fear, or aggravation.
What to Expect
During Treatment
After Treatment
Following your Dual Sympathetic Block treatment, you will likely experience some after-effects, including: a temporary eye drooping and redness, congestion, and extra warmth in your face and arm. Don’t worry, these reactions are expected and are a positive sign that the block is in the correct place. These symptoms typically last for 6-8 hours.
Other side effects may include hoarseness and difficulty swallowing. These usually resolve within hours as well.
