i think it sounds like eczma too. my DD has it on back of neck and torso and we use qv wash, sorbolene cream and baby napisan to wash her clothes. heat makes it worse but not much you can do about that. i have taken her off dairy, but it didnt do anything...

the bit on the face, couldit have started out as eczma and become infected? if so i guess the antibiotics would have cleared it up.. the only other thing i can think of is.... a spider/insect bite of some descripton? or allergic reaction to the creams/antibitics you have given, only if it got worse when you used them though i suppose.
