DD is 4 yo and has got quite a number of spots under her arm. They look a bit like chicken pox spots, but it can't be that as she had very bad chicken pox a while ago. The exten from the top of her right arm down and into her armpit, none under her left arm or anywhere else. They don't really seem to be bothering her, but I just wondered if I should take her to the doctor's? Any ideas?
