I use ultra low dose for nerve pain issues. 2mg is what I usually take and it helps with my neuropathy. I have tried almost every thing to deal with nerve issues and almost every opioid available since it's easier for docs to pass out drugs that get me high rather than dealing with root cause. The low dose naltrexone is literally a life changer for me and though it doesn't appear to do too much, on bad nerve days I have an extremely hard time even getting out of bed without it. My neuropathy that naltrexone fixes is mainly my body falling asleep. Like the feeling when you sleep wrong and circulation getting cut off to a limb. My problem is that my neuropathy is total body and hits at random times through the day so it's not a constant but when it does it, it is painful. Neuropathy is not what the drug was made for so I have to get it from a compounding pharmacy and insurance will not cover it. Also another drug that helps with my nerve issues is Human Growth Hormone but that's another one that insurance doesn't like to cover. I get it for 40 bucks for 10 vials from Europe but if I get it from US pharmacy without insurance it can cost anywhere from $300-2,600 for 10 vials.
