A lumbar epidural steroid injection is a simple, minimally invasive procedure used to relieve pain in the lower back, buttocks, and legs: often caused by conditions like herniated discs, spinal stenosis, or sciatica. These issues can put pressure on the nerves in your lower spine, leading to discomfort that may even travel down the legs.
During the procedure, the skin is numbed, and a small needle is carefully guided into the epidural space, the area around the spinal cord where irritated nerves are located. Using a live X-ray (called fluoroscopy), your doctor makes sure the needle is placed precisely. A combination of numbing medication and anti-inflammatory steroid medicine is then injected to help reduce swelling and relieve nerve pain.
Most patients go home the same day and can return to normal activities, including work, within 24 hours. You may feel immediate relief for a few hours thanks to the anesthetic, followed by a short return of pain before the steroid takes effect. The full benefits of the injection are typically felt within a week. Depending on how well you respond, you may only need one injection, or up to three, spaced a few weeks apart.
While results vary, many patients experience long-lasting relief, and some even avoid the need for further treatment. Your provider will help determine if this option fits your specific condition and recovery goals.
