Nerve Root Block

What is a nerve root block?

A nerve root block determines if a specific inflamed spinal nerve is the source of your pain.

Where can I schedule this exam?

A nerve root block can be scheduled at: 

How should I prepare for my procedure?
  • If you have an active infection and are taking antibiotics, the medication course must be complete prior to the procedure
  • Inform us if you are or may be pregnant, or have allergies to medications or x-ray dye (contrast).
  • Arrive 15 minutes early to complete registration.
  • Bring your insurance card and a valid photo ID.
How long will my procedure take?

A nerve root block will take about 30 minutes.

What happens during my procedure?

You will be positioned on your back or stomach on an x-ray table. The area to be injected will be cleansed with an antiseptic solution. Local anesthetic will be applied to numb the area.

After the needle is placed, contrast material is injected to confirm that the needle is in the correct location. A needle is placed close to the suspected nerve and a small amount of anesthetic is injected to see if it reduces your pain symptoms.

What happens after my procedure?

A summary of the procedure and findings will be sent to your healthcare provider.

Rest for the remainder of the day and do not return to work until the following day. Avoid heavy lifting or strenuous activity for 24 hours after the procedure.

After the injection, you may feel soreness or tenderness at the needle insertion site. You can use an ice pack for up to 15 minutes per hour to relieve any discomfort.
