Everytime my son comes back from his fathers I find these small black dots on him. At night thy would move all over his body and crawl into my hair. They always start from his hair and his father swears he's never seen them. After doctors appts then a rush to the er it's finally noted they are coming from him. My son came home last night covered in hives from them and had these little things everywhere. Some look like the ones in the pic and some look more oblong. I can't find any today to take new pics of because our new routine from coming from his fathers is take off our clothes bag them and take a bath. This has been killing me the past month and a half, I know this pic isn't the best but it was what I got before rushing him to the er. I feel them crawling all over me especially my head and ugg boots since they are fur lined. i swear last week there were also these little yellow bugs but i havent seen them anymore. iAny thoughts?
