I am not going to be much help, but both my DD's have developed little pimply things all over them. Not alot, just one here and there, but they are hard and like whiteheads. I am not sure what they are but will go to Doc's if not clear in a few days. Some of them look like TINY chicken pox, but it's been too long for that (they've been visible for about 2 weeks and not going away either). Kind of like blisters. Is that what your DS are like? xo
