Early last month DS got ill with a general cough, temp, under the weather. Day 4 he came out with raised red spots only on the back of his thighs and an odd on on his lower legs. Next day a couple on his arms. These spots didn't bother him and they soon went. The doctor didn't have any suggestions for what caused them apart from maybe just a viral reaction.
Since then the spots continue to come and go. They are never on his torso or face. Mainly backs of thighs and some on arms. They never bother him. The amount of them changes almost daily. The attached pic is from this morning, but yesterday he had maybe 2. This is one thigh/ leg but he has some on the other leg and arms today as well.
Does anybody have any thoughts on what they could be?
