The rashes on the skin and its persistent itching just kill you from within. If you are scratching it too much, it will convert into dark red spots and hence deep rashes, and if you won’t rub your fingers on the rashes, it will yet again be a horrible situation for you! Rashes generally appear on hands, legs, back, face, genital portion, chest area and scalp. Red rashes normally expand in infants as their skin are extremely soft, than the other age-category people.
