Medial Branch (Nerve) Blocks

Facet joints are often the cause of spinal pain. These are small joints in the back of the spinal bones and overlap each other like shingles on a roof. These joints can become arthritic and develop pain with movement. The pain physician uses a specialized x-ray to locate small nerves which give feeling to these joints and inject pain medicine and steroids to block the pain and determine which joints are causing the symptoms.
