Suggest Treatment For Pinched Nerve In Lower Back Causing Burning Sensation

A pinched nerve in my lower back on my left side is causing a burning sensation in my left leg and on my instep and toes. I have been diagnosed with lumbar radiculitis - primary 724-4. What treatment would you recommend for this. I have had therapy and presently on Gabapentin. I can walk and function without much pain, but the burning sensation comes and goes.
