I'm 17 years old. When I was a baby I had Pityriasis Rosea. You are only suppose have it once, but I had it twice. Two years ago I got it again for about two months. Now for the last two years I've had birth-mark-like spots on my stomach. The same exact looking spots as before. They haven't left, they don't itch but it's the same. Is this anything? They are suppose to go away.
