My college age daughter was home yesterday and noticed several small bug bites on her, a few on her legs but several on her torso. Not very itchy, which is unusual for her, since mosquito or flea bites lead to huge bulls eye lumps when she gets bit? Today she called me and said she now has many more pin prick red dots all over her torso and a few around her hairline, but they don t itch. She has lots around her bra line, but none between her thighs, which leads me to think it is not a heat rash. She has no fever and does not feel ill, though she got over a bad cold about 2 or 3 weeks ago. Any ideas?
