Selective Nerve Root Block


The selective nerve root block is considered as an injection that transfers medication in the space around spinal nerve roots. The main objective of this treatment is to find out the location of a particular nerve root that seems to be the reason of producing pain and with that it is to provide relief from back, leg, or other pains caused by damaged spinal nerves. The SNRB is also used for the treatment of specific sorts of disc herniation.

The process is carried out as…

  1. You lies face down on an x-ray table and the your skin is properly cleaned with an antiseptic
  2. With the help of fluoroscopy your doctor detectsa particular spinal nerve root;your doctor uses a type of X-ray that plays a video of images of your body.
  3. Once the nerve root is detected, your doctor will insert a needle through your skin into the area alongside the spinal nerve
  4. Medication steroids are to eliminate inflammation and local anesthetic for numbing is used and it is transferred into the area immersing the nerve root.
  5. If your pain gets subsided after the injection, the pain producing nerve root is believed to have been identified
