My nephew and niece have broken out on their arms, legs, stomachs, backs, and faces. We have been to 2 doctors and they only say that they are bug bites. They don't give medicine or tell us what to do for them. They are itchy. The marks also stay only for a day then go away and then when they go to bed, they are back again. I have enclosed a picture of my nephew's arm. No one else in the house has got them. My 10 month old sleeps in the same room as my niece anda she doesn't have them.
