DD age 2 has a small, half inch round patch of red skin. It's sort of leathery/crusty and doesn't seem to be bothering her. It's been there for a few weeks but briefly cleared up before returning.
In googling it seems likely to be eczema except the images of eczema look like spots and DDs patch is a flat patch rather than spotty.
Does anyone know what it might be? Would you visit a gp/nurse about it or self treat? (I have health anxiety so never know!)
