I haven't heard a lot about LDN but from what I have heard is some people use it for autoimmune illnesses like RA, MS, etc. Fibro is not an autoimmune illness.
It also bothers me that you don't hear about this much. If it really worked the wonders that are claimed it would be all over the news plus many people would be on it. Doctors would be prescribing this instead of the Lyrica, Savella, Cymbalta, gabapentin, etc that is being prescribed these days for fibro. That makes me wonder. Just my humble opinion.
