When neck and arm pain persist despite rest and other nonsurgical treatments, a cervical selective nerve root block may be considered. Although pain is the most common symptom, other symptoms and signs often occur in both the neck and/or arm including numbness, tingling, weakness, burning or other strange feelings called paresthesia.


The exact symptoms that you feel can vary but in the neck you most frequently feel pain and stiffness or reduced range of motion; and in the arm you will most likely experience a combination of pain, numbness, or tingling. The goal of this injection is to reduce inflammation for a suspected spinal nerve that is inflamed. Common conditions that might compress or inflame a spinal nerve include:

Reducing inflammation in the pinched or irritated nerve may help relieve neck, arm, or hand pain or paresthesia caused by the inflamed spinal nerve.

Cervical selective nerve root block procedure

A typical cervical selective nerve root block injection procedure takes about 30 minutes and involves these general steps:

  1. To begin a cervical selective nerve root block procedure, your doctor will have you set up in a procedure room with the area of your neck to be injected exposed and sterilized. He or she will then inject a local anesthetic into your skin over the painful area.
  2. With the help of fluoroscopy (X-ray guidance) and contrast dye, your doctor positions the needle near the nerve that is suspected of being the cause of your pain. Sometimes ultrasound is used to help visualize where to place the needle instead of fluoroscopy.
  3. When your doctor is satisfied that the needle is in the correct position, she or he will inject both lidocaine, a type of anesthetic, as well as a steroid, such as cortisone, around the nerve root near the point of irritation.

After the cervical selective nerve root block, most people can go home soon and are advised to take things easy the rest of the day.
