Some months ago, a spot of the skin over my lower spine, just above my back, became brownish and not smooth (like an eczema). At first I thought it was just a bruise healing and I payed no attention. A couple of weeks ago, I noticed that there were two spots now, one above the other and this week I noticed that I have the same spot on my foot, on the skin over my ankle. It's not iching, it's not disturbing but it's speading. What is it? Can you help me. I think of the worse senario.
Thank you
