I have this deep purple, bruise look alike on the side of my foot, it started of as a small patch which made me think it was a bruise but I just cant remember how I got it, but this thing is keep getting bigger and bigger and turning a more deeper purple, which then made me think again and came to realize that its not a bruise, it doesn t hurt much when I touch it either, like not as a bruise should feel, what is this and what do I do?
