sympathetic block

What is a Sympathetic Block?

Originating in the spinal cord, your sympathetic nervous system controls all of your body’s involuntary reflexes. These nerves influence bodily functions such as: Blood pressure, sexual arousal, urination & defecation.

A sympathetic block is the administration of a local anesthetic into a sympathetic ganglion. This can help with pain management for disorders that involve your sympathetic nervous system.

What does the procedure look like?

This entire procedure takes less than 15 minutes and is an outpatient procedure, performed in the Portland Pain and Spine clinic. Once the injection site is numb and you are comfortable, your doctor will insert a second needle near the targeted ganglion. Using X-ray guidance, your doctor will inject an anesthetic, and a corticosteroid into the area near the sympathetic nerve ganglion.

We want to assure our patients that Portland Pain and Spine remains open and actively managing your pain. Medication management is given the highest priority. Our relocation across the hall in the Washington building is complete but requires office renovation before we can accommodate patient visits. Staffing shortages affected our ability to communicate last month, however, this was temporary. Dr. Balog has reached out to all patients but asks that if anyone has additional questions or concerns to contact him at
We have updated our phone messaging system to assist with calls. There are now options to speak with a live receptionist, leave messages or speak with our new billing company. Medical record requests can be processed on our website at and are handled by Morgan Records Management. Thank you for your patience during this transition. We look forward to providing you high-quality care as we enter into 2024!
