If you have low back pain and sciatica, you may have tried many different treatments to find relief and to improve your ability to function. Your doctor may prescribe medication, physical therapy, or spinal decompression to attempt to treat your problem.
Epidural steroid injections are another common way to non-surgically treat the low back and leg pain associated with sciatica. The medicine is usually a steroid that is injected in your spine near the inflamed lumbar nerve. This steroid helps to decrease pain and swelling around the nerve root, and thus, offer relief from sciatica.
A study recently published in the Annals of Internal Medicine examined the effect of three different injections in the spine. The researchers randomized 85 patients with lumbar radiculopathy of less than 6 months duration into three groups. One group received injections of steroids, one group received etanercept (an arthritis medication with the trade name Enbrel), and the third group received normal saline injections. All participants received two injections spaced two weeks apart.
The main outcome measure in the study was leg pain one month after the second injection was administered.
The results indicate the there was more improvement in symptoms with the epidural steroids, but the improvement was not statistically significant when compared to etanercept or saline. That's right-your doctor could possibly inject salt water into your back to treat your lumbosacral radiculopathy, and this may help improve your pain level just as effectively as steroids. Of course, your doctor would never do such a thing, but the thought is pretty interesting.
Bottom line: for a specific group of patients, injection of steroids into the spine can help with the pain associated with sciatica. The trick is identifying those people, and identifying those patients who would not benefit from such a procedure.
