Cervical Selective Nerve Blocks


Cervical Selective Nerve Blocks is an injection procedure used to identify the source of nerve pain in the neck to provide long-term pain relief. The nerve pain in the neck radiates down into the shoulder, hand, and arms. It can develop when a cervical nerve root is compressed or inflamed due to a herniated disc, spinal stenosis, or other degenerative spinal changes. The doctor injects a contrast dye to aid correct placement of the needle at or near the suspected irritative or compressed nerves. Once the needle is safely placed, a second injection is injected into the nerve root where it exits the foramen, a side opening where the two vertebrae meet. If the patient’s nerve pain disappears, then the correct nerve root has been identified.
