I had polyneuropathy for over 10 years and I have been on every medication I have seen listed on these forums and a few of them, like gabapentin, lyrica and cymbalta seemed to make it worse when I had to stop taking them when I lost my insurance due to unemployment for a while. During that time I was so desperate I tried so many natural things and 2 things have helped more than any narcotic or antidepressants or anticonvulsants - Kratom. It is legal in most states but not all because it is highly controversial but it literally saved my life. Also a suppliment called Alpha Lipoic Acid contains 600mg. I pray you find relief because it’s seriously the worst pain I ever imagined a human would gave to endure and which the medical field seems to be completely heartless about (unless you happen to find an actual doctor who has lived through it.) The only other thing that ever helped me was Valium or Xanax and the doctors would rather someone take their own life than allow that so I had no choice but to desperately search for something and thank God I found Kratom. It comes in capsule or powder form and if you take it regularly for chronic pain so you are not chasing the pain it really helps but it is definitely addicting physically so you can’t just stop taking it cold Turkey (like any of these other hardcore meds they are passing out. It also helps mood and energy depending on the different strains. The red ones are the ones that keep my neuropathy calm the best but they all work.
