I have purple splothes on my lower legs, mainly in the front. They are not bruises. They fade within a week or so and then others appear. They are different shapes and range from small to about 3 inches. What causes them and what can i do to get rid of them? They started last summer and went away briefly for a few months. I have seen a Dermatologist, a Vasclar ssurgeon, had a Dopler test, and numerous blood work. My blood work is fine and so is my circulation. I am 74 and female. Please, can you shed some light on this condition?
