Hi, my 13 yr old son has got holes in thick skin on the ball of his foot which looks like it could be pitted keratolytis, now my 4 yr old daughter got a rash all over her torso and legs which felt rough, then her fingers and palms started peeling with air filled blisters which sounds like keratolytis exfoliata, 2 weeks aftr peeling she now got a fever, abdo pains, headache, says her legs are hurting, wonder if the keratolysis might be linked with them both
