I Have Reddish Spots On My Legs From The Knees

I have reddish spots on my legs from the knees down and the tops of my feet. They are not raised and do not itch. I know they are not chigger bites or mosquitoes. It doesn't look or feel like razor burn. They look like chickenpox but again, not raised and not itching. They just look awful and I don't know what to do to get rid of them.
