I have white spots on both of the lower portions of my shins. I have no idea what they are. They go away when I rub them, then they come right back after the rubbing. My mother says it might be because of bad circulation, but I don’t trust her at all when it comes to health advice. She’s screwed me over by following her advice a couple of times. I’m just wondering if the white patches on my legs is something I should worry about and if anyone has any ideas about them. I also have PCOS, if that contributes to anything this.
