my 4 yr old has 5 spots on his nose, they look like pimples, bumps, blackheads under the skin, when i tried to pop one, a little fluid came out, but it still had the black dot under the skin, and with in a day or two it looked the same, it started about a year ago, but i think it looks worse now, and he says its itching at times, his father had freckles when he was a child, could it be it ?
