I have had one smallish brownish red blotch on my belly for about two years. Last week, I noticed a second. Now, I have at least three more. I have the one on my belly, one under each breast, and one on the underside of my breast. They range in size from a few centimeters in diameter to the size of a dime. They don't hurt, itch, or seem to be irritated in any way. They simply appear to be discolorations. I haven't been out in the sun in a bathing suit for eight months. What could these be? I am female and 35.
