Hi Scottish Andy,
I am 3 years post surgery and on Gabapentin as well as a myriad of narcotics. None really touched the leg pain. Recently I was given Wellbutrin to help with a persistent problem with lethargy. To my surprise the nerve pain in my legs disappeared within 2 days. It's not the intended use but somehow worked for me. It's only been a couple months but I'm loving it. Worth a try maybe?
