Hi aunty, to answer some of your questions first of all they do not itch. I don't know exactly when they started occuring this time but I know it was sometime in early Spring late winter of this year. They are mostly on the back of both of my legs going all the way up to my thighs. Some are on the front but below the knees extending down to my feet. It is hard to describe, exactly what they look like. Let's say I cut myself on the leg, during the time of its healing I have been sun tanning. When the scab falls off the color of skin that is left would be lighter. Sounds pretty stupid but that is the only way to describe them. I do have a scar on my leg and when I was looking to see where all the blotches were I noticed my scar appeared to be the same color as the blotches. Hope this helps. Thanks for responding.
