So I noticed today, that on my arm... Forearm area, there's two small dark spots next to each other... Round and ruse up a little bit. Almost like tiny moles but I've never had moles. Their odd enough to make me nervous... I've seen brochures about like melanoma & things like it and I'm not saying that's what it is but I'm not sure what else it could be? Does anyone know what it could be? And is it worth going to have it checked out right away?
