I finally got what's probably the correct diagnosis for the itchy skin that's plagued me for the past 6 months: candida overgrowth, which can happen while on LDN. (and following taking an antibotoic, as happened in my case). The dx came from my alternative MD; I didn't realize candida could make one's skin itch, but this makes far more sense than to think I would develop an autoimmune problem like eczema (said the dermatologist) or worsened food allergies (said the GP) while on LDN.
I've stopped the LDN and will do thorough candida testing and treatment., The alt MD uses long-term diflucan, which makes me nervous as it has many potential side effects, so I may try some herbs first. (And I already tried a packaged candida cleanse plus digestive enzymes and probitoics, but that hasn't been enough to lick it).
The transition off LDN, from 3 mg every other morning, has gone fine. I haven't noticed any difference except that some of my under-eye swelling (TED) has returned and the eczema on my palms is threatening to flare. I look forward to getting back on LDN after dealing with the yeast.
