I noticed yesterday that my son had a spot on his neck. I thought it was dirt at first and tried to wash it off. It didn't budge and I called the Dr. today and got an appointment. No itching, no fever, no symptoms other than the sudden dark spot. It is red all around and irregularly shaped, raised and it even has different shades of brown and black. Can a mole just come out of nowhere? The doctor said it was a bug bite that he has scratched and made blood come to the surface. I never saw him itch it and he doesn't complain about it at all. Please let me know what you think.
