I've been noticing a black line across my cuticle on my thumb, and it's been worrying me a bit. The skin behind it seems slightly inflamed, but the line doesn't go the entire length of the cuticlejust about halfway across the more horizontal part. It's really thin, less than a millimeter. Should I be concerned about this? Does it sound like something I need to get checked out?
