I take R-ALA, evening primrose oil, and benfotiamin ( a fat soluble form of vitamin B1) and they have helped my neuropathy. The R-ALA and benfotiamin have been studied in Europe and both are used for neuropathy there. Getting better control of my blood glucose also undoubtedly helped too. Here’s a recent discussion about this. Here’s another link that references a study that says it may take 2 - 3 years for your nerves to heal, and explains what is going on that causes the condition.
As regards medical marijuana, all there is is anecdotal evidence, because the government is terrified that actual scientific evidence proving its efficacy will cause even more agitation for legalization. Advocates contend that it is not a pain killer per se but instead makes the pain easier to tolerate, no small thing if you’re the one in pain. The issue is really a political one and not a medical one and goes back to the extreme polarization on this and many other issues during the 60’s. Both sides have dug in their heals and a resolution of this question, based on science, is impossible at present.
