Hello, My husband recently has had a wide range of tiny raised aboved the skin spots. they are a little reddish, but he is dark so mostly skin colored. They don t seem to bug him but it is spreading more and some are bigger than others. It ranges from his neck , chest , back and stomach all the way down to some parts of his upper legs. He isn t allergic to anything that we know of or using anything to cause a reaction. what could this be?
