145 patients with lumbosacral radicular pain secondary to a herniated disc or spinal stenosis for less than 4 years where randomized to receive either epidural steroid injection plus placebo pills or sham injection plus gabapentin. Average leg pain was assessed over 3 months to evaluate whether an epidural steroid injection or gabapentin is a better treatment for lumbroscral radicular pain. Both treatments resulted in similar, significant improvement in pain scores over 3 months. Epidural steroid injections offered minor benefits in secondary measures at 1 month, though differences at 3 months were not statistically significant.
