The goal of lumbar epidural steroid injection is typically to provide adequate short-term pain relief so that you can begin or continue physical therapy or to try to avoid more intensive pain relief procedures. Physical therapy may help promote long-term pain relief by strengthening the muscles that support your spine.
If a lumbar ESI works for you and results in pain relief, your healthcare provider may recommend another injection later on. However, most providers limit people to two to three ESIs per year.
Studies on lumbar ESIs have revealed that they can provide reliable pain relief for up to 6 months in many cases. However, every person is different and experiences pain differently, so your experience may vary.
Lumbar ESIs are most successful at providing temporary pain relief for radicular pain caused by a lumbar herniated disk and lumbar spinal stenosis. One study revealed that for people with radicular pain secondary to disk herniation who received a lumbar ESI, up to 70% of them felt at least 50% better at one to two months, and 40% of them felt better at 12 months.
It’s important to remember that lumbar ESIs are not intended to cure back pain; their main goal is to provide pain relief.

Rather, it will provide pain relief so that you can return to your normal activities, improve your quality of life and complete physical therapy. If you’re feeling anxious about receiving a lumbar ESI, don’t be afraid to ask your healthcare provider about it and the procedure. They can answer any questions you may have.
