An epidural steroid injection is a common non-surgical treatment option to help alleviate pain in the upper spine/neck caused by irritated nerves. This choice of treatment is focused on pain relief and the results are temporary. However, combined with a rehabilitation program, short-term pain relief can be beneficial. The steroid that is injected reduces inflammation and therefore reduces painful irritation. This can be a treatment for herniated lumbar discs, degenerative disc disease and lumbar spinal stenosis (or a narrowing of the spinal canal that compresses nerves and the spinal cord).
