The only things that I have found that is OTC are CoQ10 (often recommended for anyone on a statin for cholesterol) and turmeric. My wife actually gets more relief from the turmeric than I do for muscle tension pain. I take it and antioxidant supplements for inflammation since that is one of the primary pain factors for my pancreatic pain. I think inflammation is responsible for much of our bodily pains, but that is just a lay person's belief. I do not experience pain with neuropathy right now, but have the tingling in hands and feet. I hope this helps a bit, but I don't have any specific experience with your form of neuropathy, but there will be some others who will jump in here.
