If you suffer from chronic low back pain, leg pain, buttock pain or sciatica that has failed improve with time and/or conservative therapy, you many be a candidate for this quick and simple treatment option.  A lumbar epidural injection (aka lumbar epidural steroid injection or LESI) is a safe, effective, and minimally invasive treatment. LESIs have been used to treat certain types of low back pain, buttock pain, leg pain and sciatica for decades. It is a procedure very similar to the epidural a woman will receive to deal with the pain associated with childbirth. With a lumbar epidural injection your doctor will place a small amount of anti-inflammatory medication into the epidural space NEAR the spine – not on it or in it. This will relieve swelling, inflammation but most importantly – PAIN.
