my daughter is 15 years old, and since she was a small child has had extremly red cheeks when she would get hot. the cheeks are hot to the touch. over the last 6 mos. it has started to become spotchy, red blister like marks (not raised in any way), that cover her neck, face, chest, hands, feet, ankles. it does not itch her nor does she complain of any pain. it typically happens between 10am and 2pm while she is at school.
