This is an injection of a local anesthetic or more often a combination of a local anesthetic and a steroid adjacent to a nerve that is being pinched or irritated. This is performed under guidance of an X-Ray machine. The needle is expertly placed very close to the nerve, contrast is then injected and the spread is monitored under live fluoroscopy. If the contrast spreads along the affected nerve root, the steroid is then injected. The patients often receive sedation during the procedure rendering it near painless.
