Transforaminal Injections are used to treat back and leg pain due to a herniated disc and/or nerve pressure. The procedure consists of injecting medicine in the neural foramina space in one of the lumbar intervertebral levels. First a local anesthetic numbs the injection site. Then contrast dye is used to ensure proper placement in the epidural space. Finally the treatment, which typically consists of corticosteroids and anti-inflammatory, is injected. These long acting steroids can reduce swelling as well as inflammation of the spinal nerve roots and surrounding areas. Discussing the benefits and risks with your doctor is strongly encouraged; results vary on a case-to-case basis.
