What do I need to know about a caudal epidural injection?

Treats back pain. Injection of steroids in the epidural space have been used for decades to treat low back and/or leg pain. The caudal approach means that the medications are introduced into the spinal canal near the tailbone and fluid is used to push the medication up to where it is needed. It is most often used to treat pain from disc herniation or spinal stenosis.
See below. Caudal epidural steroid injections involve injecting a steroid into the epidural space, where the irritated nerve roots are located. The caudal injection is performed through the sacral opening and is used to treat low back pain. This injection includes both a long-lasting steroid and an anesthetic (lidocaine, bupivacaine).
