I have tiny red bumps that popped up on my shoulder, it is also on the side of my neck under my ear a day later it was on the other side of my neck. It looks like Miliaria rubra but I will now have had it four days and it seems to be coming up on the other shoulder. It does itch but only randomly. I also think its coming up on the side of my face by my hair line. And there in clusters... please help!
