Title: Randomized, Double-blind, Comparative-effectiveness Study Comparing Epidural Steroid Injections to Gabapentin in Patients With Lumbosacral Radiculopathy
Brief Summary: The purpose of this study is to determine whether pharmacotherapy or epidural steroid injections are a better treatment for lumbosacral radicular pain.

142 patients referred to a participating pain clinic with lumbosacral radiculopathy will be randomized in a 1:1 ratio to receive one of two treatments. Half (n=71) of the patients will be allocated to receive an epidural steroid injection (ESI; group I), with an equal number allocated to receive gabapentin (group II). Patients \& evaluating physicians will be blinded. Follow-up will be through 3-months after treatment.
