The source of pain in your body may be different from the location you are experiencing pain. In order to properly locate the source of pain, a controlled comparative nerve block can be performed. A therapeutic injection is intended to treat the affected area by blocking the nerves coming off of the facet joint. This process is known as Facet Joint Nerve Block.
Your spine consists of three areas: cervical (neck), thoracic (upper back) and lumbar (lower back). The small bones that make up the spine are known as vertabrae. The cervical area of the spine has 7 vertabrae, while the thoracic has 12 and the lumbar has 5. Facet Joints are where the vertabrae join together. On the top and bottom of each vertabrae, there are two facet joints. The nerves connected to each of the joints send pain signals to the brain. Such pain could be the result of arthritis, thinning of the cartilage or injury of some sort.
