Hello ma'am. Your description of the skin rashes is not adequate for me arrive at a conclusive diagnosis. Generally the skin rash does not have much relation with the diet and personal hygiene. Do you experience just plain itching or skin rash. If you experience just redness
, is it like wheals (elevated transient patches which are intensely itchy and subside with few hours to leave behind normal skin) or you get persistent elevated lesions which remains for days together? It could be just acute urticaria
or exanthematous eruption.
