Cary,
Low dose naltrexone (LDN) is indeed used for pain management (although it also has other uses, such as treating Crohn's disease and MS). For pain it is most commonly prescibed for neuropathic pain -- especially conditions like CRPS, which is what I take it for -- as well as central pain. At low doses (usually 1.5 - 4.5 mg, and no more than 10 mg), it works differently than at full strength (50 mg+, which is used to treat opioid and alcohol dependency). At such low doses it is not a strong opioid antagonist, but rather works primarily as a glial cell modulator, reducing inflammatory mediators in the brain & central nervous system, increasing endogenous endorphins and enkephalins, and also strengthening the immune system. Most doctors in the USA don't know much, if anything about LDN, which is why you are probably not familiar with it. Although it is used much more commonly in Europe. It also has to be compounded, so it isn't something a regular pharmacist would mention or suggest, either. But there have been a lot of studies done on LDN for CRPS, fibro, and a whole slew of autoimmune diseases, with promising results. Personally, I have been on it for 4 mo now (put on it by my PM, who is an expert in CRPS, and has been using LDN for many years), and it has made a huge difference in both my pain and fatigue, and works much better for me than any opioid or other nerve pain medication ever did. But you do have to be careful not to take it with opioids (at least not with in a few hours of each other) because the LDN still is a weak opioid antagonist, and could potentially put you into withdrawals if taken together. Which is why Thoreau couldn't take the LDN and tramadol at the same time.
