He has had what I think are heat bumps on his ears when the sun comes out. He had it last summer and it looks like nettle rash but its definately related to the sunshine. During the winter it doesnt appear at all.
Ds is 10 yrs and very fair skinned, but with dark hair. His Dad is a redhead with blond eye lashes and blond eye brows so very very fair skinned.
His right ear looks really awful today after school, with all the pinna area totally covered in white bumps.
What is it ??
