I have tried tons of remedies for dyshidrotic eczema and finally found what worked. I have read that it may be due to a nickel allergy. Vitamin c and iron block nickel absorption. I started taking a timed release vitamin c and a multivitamin with iron(one at lunch and the other at dinner)and the itching and rash is gone. Other things that may have helped are making sure I'm getting enough iodine, taking a fish oil/flax oil supplement, using liquid bandage on the flare-ups and sudocrem at night. I also have hypothyroidism, which could be linked, and started taking a thyroid support pill I found on amazon for that. Hope this helps someone.
