Our physicians understand the importance of an absolutely accurate diagnosis. To arrive at this diagnosis, they utilize diagnostic injections combined with the most sophisticated imaging technologies. Our physicians use a variety of injections, also know as “blocks,” to diagnose and treat nerve and spinal joint irritations. The blocks involve an injection of a steroid drug at the nerve root or joint that is suspected of being at the source of the patient’s pain. The most common blocks are Selective Nerve Root Blocks (SNRB), Sympathetic Nerve Blocks, Facet Blocks and Epidural Steroid Injections (ESI).
