I have these little black dots under my boobs some stick out and others dont. Some hurt and can be itchy when i squeeze on them some puss out and others dont this has been going on for about a couple years. Now I started noticing them on tops of my legs but were a lil different like bites but very itchy and marked up fast but in the center is still that little black dot. So I have a black head and white head issue on my nose. The other day I used a black head remover strip and the first layer of skin got torn off, when that hapoened i noticed a few of those supossibly black heads were the same little black dots that wont budge. Then last night i noticed a few black dots on my arm when i tried to pick them out they won t budge and make a snapping noise and goes right back into place. Im freaking whay could this be?
