Steroid injections have been used to help give relief for pain caused by inflammation. One of the more common areas in the back and spine to experience pain due to inflammation is in the lumbar or lower back region. The lumbar region of the spine carries the majority of weight, making it more likely for damage to occur in this area. When inflammation occurs around the spinal canal, pressure on the nerve roots can cause severe pain, numbness and even muscle weakness through the lower back, hips and legs. Lumbar epidural steroid injections are a treatment option that can temporarily reduce the inflammation and help manage lower back pain.
