I wonder if this is detox related in some of those people? During my first 3 days I noticed that I had something break out around my fingers. I didn't notice it until I stuck my hand in potato seasoning salt and it burned like crazy and then I saw the little red flakes and 3 little blisters on the base of my right index finger. I used to get that a lot when I was ages 17-20... seemed to have been brought on as an allergy to dish soap. But after a round of Antibiotics for something or another when I was 19 or 20, it went away and never came back again.
This time it was gone the next day so I wondered if it was Iodine pushing something out and I never thought about it again until this was brought up.
