An epidural is an outpatient procedure for the treatment of lower back pain caused by a damaged disc. The damaged disc may create pressure or irritation to the surrounding spinal nerves. Conditions such as disc bulging, disc herniation, disc degeneration, and spinal stenosis are all commonly known to create pressure or irritation to spinal nerves. However, these conditions may not always create nerve irritation.
This a single injection is given in the spine at the level of the problem using steroids with a numbing agent. This procedure is performed under fluoroscopy to ensure proper needle placement into the epidural space.
The effects of the steroid can take 2-5 days before pain relief may be noticed. Once the steroid takes effect, you can expect 4-6 weeks of relief. It is not uncommon to experience more pain relief in the legs vs the back. These injections can be repeated up to 4 times a year.
