Hi there,
I've had a small spot on my arm since my teens: it's not painful, uncomfortable or itchy, not raised or lumpy, the only difference with the surrounding skin is its dark-blue color. I have never paid much attention to it and it has never changed for the 10+ years it's been there: it hasn't gotten bigger or smaller, or ever done much of anything except, well, be there and blue.
A friend of mine recently recommended I have it checked, and I have two questions: what are the possible explanations, and is it worth mentioning to a doctor?
Thanks in advance!
CA.
