A Cervical Epidural Steroid Injections (CESI) is an injection of cortisone steroid in your cervical spine (neck). The spinal cord is made up of tiny bones called vertebrae. Between each vertebra there is sac called the dura which contains the nerve roots, cerebrospinal fluid, spinal cord, and nerves. There is a space around the dura called the epidural space which the nerves in the cervical spine travel through before going down the shoulders into the arms and hands. If one of these nerves in pinched or irritated, you may feel pain along the path in your shoulder, arms, or hands. This is called cervical radiculopathy.
A CESI uses a steroid to reduce inflammation to the nerves and therefore ease pain. The doctor will use X-ray guidance called fluoroscopy to position the needle in the epidural space. Once the needle is positioned, the doctor will inject a cortisone steroid solution.
