I have a blister on my mole, I squeed it lightly and blooded popped out. I haven't strach my mole or anything. The looked like there was dry blood on it, but there wasn't any dry blood. This mole always does this, then heals, and then the smae thing will happen again. i alway have to moles on my chest that look like threre is red skin on them, they itchy and bleed something. Do I need to get them check out?
