Once again you come to my rescue!! I am keeping my fingers crossed. Hope it works. Had another Derm appt. today to re-check where the patch had been. Defintely no cobalt allergy. Nothing at all. She said its contact dermatitis not atopic. I was told in the past it was atopic. Can't figure out what I could be touching on the tops of my hands and fingers but not on the palms. Doesn't make sense. Except for latex allergy maybe. But it's also on my ears, neck, crease of elbows, and forearms. I am drinking 2 tbsn ACV w/ 1/2 tsn baking soda in water 3x day. So far no change. Will keep you posted. So sick of the itchiness and redness. Thanks Mackenzie!
