I have NO allergies, but i did get bumps like you are describing, except mine were on my breast bone... they became red, VERY itchy, to the point where i couldnt sleep, and had to put a wet towel on my chest to "cool" them down since they burned so much.. some of them looked like "zits" but weren't poppable. I was told by my doctor that it was a form of detox, coming through the skin, the toxins. But i didnt get these bumps until day 30, and i stopped the fast on day 35... they eventually faded away... So i dont know if they are as you're wife's bumps, but it was just detoxing for me.
