Sympathetic Nerve Block

A sympathetic nerve block involves injecting medicine around the sympathetic nerves to either temporarily or permanently reduce or eliminate pain.

Before Your Procedure

  • Some medications may increase the risk of bleeding after your procedure. Please check with your doctor about possibly holding medications such as aspirin, Coumadin (warfarin), Ticlid, Pletal, Aggrenox, Plavix and NSAIDS, such as naproxen and ibuprofen before your procedure. Please hold these medications as directed. You may resume these medications the day after your procedure.

During Your Procedure

  • Your skin will be cleaned and then numbed with medicine.
  • The doctor directs a small needle, using X-ray guidance to the area of the sympathetic nerves.
  • Medication is then injected into the area.

After Your Procedure

  • You will remain in the Imaging department to be watched and reassessed by the nurse for 30 minutes before leaving.
  • Rest for the remainder of the day.
  • You may resume your normal activity the next day. Notify your doctor if you have any signs of infection at the injection site such as redness, drainage, tenderness or if you run a fever.
  • Your doctor will be contacted with the results of your test and will discuss the results with you.

Providing safe, quality patient care is our highest priority. To help ensure quality and safety, we ask that you do not bring young children with you to your appointments, as children are not allowed to accompany you during Imaging procedures. Staff is unable to monitor your child in your absence.

If you have any questions or concerns, please contact your provider.

Dear Friends and Neighbors,

CentraCare care givers have been working around the clock for more than 20 months to care for you, your families and friends during COVID. We are committed to caring for every Minnesotan who needs us, and nothing will prevent us from doing so – even during these never-seen-before times.

The challenge of providing this level of care is that our hospital beds are often full. ERs in all of our hospitals are packed. And our clinical teams are exhausted. Early in the pandemic, our community stepped up in amazing ways to help us. We ask that you again join us in fighting this pandemic together.

How can you help?

  • Please get your COVID vaccines and booster shots. They are proven safe and effective in reducing COVID illness, keeping people out of the hospital, and preventing death.
  • If your situation is not an emergency, please use other care options, including:
  • If this is a medical emergency, call 9-1-1, or visit the ER.

Together, we can do this. Thank you for your support.

Ken Holmen, MD
President and CEO
