Have You Ever Heard About Intercostal Nerve Block?

An intercostal nerve block is an injection medication that help relieves pain in the chest area. Intercostal nerve block can be used to treat or cure pain caused by herpes zoster infection or a surgical incision. Intercostal nerve block is also helpful at the region of abdominal wall.

Intercostal nerves are located under each rib from the spine in the back to the sternum in the chest. When one of these nerves or the tissue around intercostal nerves gets irritated or inflamed, it can cause pain.

  • At the start of the procedure, you’ll be given an intravenous medication to relax you.
  • The doctor will then use antiseptic to clean an area of skin near your ribs.
  • A needle is then inserted through the skin, muscle and soft tissues, so there is some slight discomfort involved.
  • Doctor uses x-ray guidance to insert second needle and inject a steroid pain medication in the area where you are experiencing pain.
