Hello everyone, I have a 14 month old who keeps getting this big look alike pimples on her butt checks since she was 8/9 months. They get very painful that she does not like to sit. I’ve seen many doctors and they can not tell me what she had I get no answers just medicine. I dont want to be giving her medicine if they don’t know what it is. I don’t want to go giving her something if they don’t know it will do anything. I’m lost frustrated and worried
