My child is 5 and has had this rash for several months now. The bumps are not close together, clear, raised and do not itch. However, they do seem to spread. I thought it may be a form or eczema and have been apply Elocon cream .1%. It is not helping. This rash doesn't bother my child but it seems to be spreading. They look like tiny pimples that can not be popped. Any idea what this could be?
