A selective nerve root block may be performed to determine if a specific spinal nerve root is the source of pain and reduce inflammation around the nerve root thus decreasing or relieving the pain (e.g. siatic nerve). Patients are given a local anesthetic or IV sedation then the physician will locate, with the use of fluoroscopy, a specific spinal nerve root. A needle is introduced through the skin and into the area adjacent to the nerve root. Medication, an anesthetic and a steroid, is then injected into the area bathing the nerve root. Selective nerve root blocks typically take 30 minutes and can be done in the office.
