So about a month ago I found a little bump on my daughters belly. She's three months old and the bump has grown to a size of a pea and has gotten dark. She's mixed idk if that has something to do with it. We've taken her to a pediatrician but she looked at it for two second and assumed it was a mole and gave me discharge papers and left the room she was in a rush so I feel I didn't get an accurate diagnosis . I'm very concerned because I noticed today its got smaller bumps around it and its has became very dry . she sometimes fusses when I touch it . what could it be?
