Hi my name is Ana I am 24 years old and about 8 months ago I noticed freckles brown spots appearing on the top of my feet and on the sides. it s not bumpy and very similar to What freckles would look. I m kind of worried because they have not went away and sometimes change in color when my feet are cold they get more purplish but usually they look Brown. is this something I should be worried about I was thinking it was just from Sun exposure but now I don t know what you think what could this be and what could have caused this?
