EPIDURAL STEROID INJECTION (ESI)
Epidural steroid injections (ESI) are used to treat a variety of conditions that cause unrelenting back pain. In some cases, ESI can delay the need for surgery. Some estimates suggest that, between, 10%-20% of the population suffers from some sort of chronic back pain. There are many reasons someone might experience continued back pain – issues with facet joints, torn or inflamed ligaments, strained muscles, and irritated nerve roots.
