Dan,

I am not aware of any OTC drugs that are effective for neuropathic pain. In fact, the prescription drugs are generally only good for providing "modest pain reduction." It is probably going to take some time to figure out which combination of these drugs will help the most. If you don't want to use Gabapentin or Lyrica, there are low dose anti-tricyclic antidepressants that have show some efficacy in treating neuropathic pain.

Good Luck
