Cervical Interlaminar Epidural Block is an outpatient procedure performed to treat the neck, upper neck, shoulder, and arm pain. During this procedure, a corticosteroid is injected into the epidural space in order to reduce inflammation. The surgeon starts by injecting a local anesthetic to numb your skin, then he/she will insert a thin needle directly into the epidural space. Fluoroscopy, a type of X-ray is used to ensure a safe and correct position of the needle. Once the doctor is sure that the needle is perfectly positioned, the medicine is injected.
