What are these tiny, pinpoint size, specks that appear on my skin all over? They appear, burn and instantly disappear. Sometimes singly, sometimes in unison in a row, or in a cluster. Groups above are small so far, maybe only as many as ten. They do not wash off with ketoconazole shampoo. Clotrimazole helps a little. I do have some visible, what looks like yeast, on my legs and arms. Sometimes there is a flare-out feeling of invisible fluffy clouds. Ive been to dermatologist. He said allergies. I dont believe it.
