Hey guys,
I have these white spots on my calves and the inside part of my arm. They sometime also appear on the front part of my arm but are not quite as visible. They do not itch, hurt, and are not bumps but I have noticed my skin is usually cold is the places I get them. Also they go away on my arms if I raise my arms above my head but when brought back down they reappear. I have had them since middle school and am now in college. My brother who is in high school has the same exact thing that I have. I have also attached a picture. Any help is appreciated.
