Does anybody know what this is? Showed up a few weeks ago but coud have been there longer. I wear shorts most of the time and my legs are tan and you can't really see it. The picure makes it much more prominent. I noticed it on my feet first because of the contrast. Doesn't itch or burn or flake or anything like that. Causes no discomfort at all. Kind of like to know whats going on. Can't afford the doctor at this point. Thanks can't seem to get the pic to work.
