Treatment of chronic back pain by means of injection is not a new phenomenon in medical science. In fact, the use of injections for the treatment of chronic back pain can be traced back to the beginning of  20th century. It was around the mid-1950s, that the first injections were invented for the treatment of lower back pain sciatica. These injections were epidural and were exclusively used for the treatment of lower back pain. They were a major success in alleviating the pain associated with lumbar disc herniation.

Generally speaking a chronic epidural back pain injection is used in the treatment of pain in the lower part of the spine and the region in and around the groin and the legs. The injection is primarily used to provide relief and can take anything from a week to a year to cure the patient completely. It is exclusively used to rehabilitate patients suffering from chronic pain. Hence, it is prescribed along with the normal  side rehabilitation procedures such as physical exercises and other allopathic medications. The injections have been found to have a success rate of 50% success rate in patients suffering from the pain.
 
Any chronic pain can be associated with inflammation and swelling of certain parts of the body . This is referred to as lumbar disc herniation in spinal pain. Steroids are found to be effective in such case as it delivers the medicine directly to the region of inflammation
The epidural space comprises of a region between a membrane known as the dura matter and the outer wall comprising of vertebral matter. This region is filled with numerous blood vessels and fats and it is this region where the steroid is injected into. The area is just analogous to the dural sac. The epidural injection comprises of a flushing out substance which flushes out toxins from the region. These substances could be something like the general saline or lidocaine and the injection may also be helpful in  flushing or cleaning out proteins that are highly inflammatory in nature.
