Selective Nerve Root Block
A precise injection at one specific spinal nerve to help identify the source of arm or leg pain and calm it.
What Is Selective Nerve Root Block?
A selective nerve root block is a targeted injection of numbing medicine, often with a steroid, placed right next to one spinal nerve as it exits the spine. It can serve two purposes: helping confirm which nerve is causing your symptoms, and reducing inflammation around that nerve.
Conditions It May Help
- Leg pain (sciatica) or arm pain from a pinched nerve
- Herniated discs
- Foraminal stenosis (narrowing where the nerve exits)
- Planning for possible surgery, by identifying the pain source
How It Is Done
The skin is cleaned and numbed. With fluoroscopy (live X-ray) and contrast dye, Dr. Rema guides a thin needle to the opening where the selected nerve leaves the spine. The procedure typically takes about 15 to 30 minutes.
What to Expect
You will be asked to note how your pain changes in the hours after the injection, since this helps guide diagnosis. Temporary numbness or weakness in the arm or leg can occur. The steroid may take a few days to take effect. Most people resume normal activity the next day.
Possible Side Effects and Risks
Temporary soreness, a short-term increase in pain, or temporary numbness. Uncommon risks include infection, bleeding, headache, nerve injury and steroid-related effects such as flushing or higher blood sugar. Dr. Rema will review your medical history and medications, including blood thinners, before your procedure.
