does anyone know what this could be? I took him eating to the doctor and even they weren't sure, their thinking about some kind of fungus. they gave me a cream for it. (he's at his mom's for the week so she probably won't put it on him.) they also did a swab of his throat to make sure it's not strep and a swab of the rash and Blood work today

it's under his nose, chin, and on his forehead and cheek
