My son had what I thought was a little black mark mark on his arm the other day but when I tried to wash it off it would not come off. It didn t look like a scrape either now a few days later it is red and bumpy. It no longer has the black color to it
Howell come to ChatDoctorThe black spot may be the mole and this can not be removed and should never be tired to remove this, only need to keep eye open against this for any changes, hope this information helps.
