I am 16 years old. I am a vegetarian and could be anemic, but take iron tablets, and unsure if this is related to diet. I have a red honeycomb pattern on my skin, most noticable on my lower arm and leg, all the time, except when I am really hot. When it's a very hot day or if I've just got out of bed, my skin looks normal, but if I get even the slightest bit cold, the pattern starts to appear. It makes me very self-conscious and I can't figure out what it is or why I have it. I think I've had it for a while, but can't remember how long. When I was younger I didn't really pay attention to things like this. What is wrong with me?
