I was at the lake this past weekend around lots of people. I woke up one morning with small, red, bumps on my legs. Only one of my friends got them too. I'm pretty sure they're bites of some type, but I don't know what. I don't think they are chiggers (red bugs) or fleas, because they do NOT itch. I don't know if it's my imagination, but I didn't notice them on my back the first day, but the second day I did. They were probably already there, but I'm not positive. Please help, I'd like to know what these little bites are from.
