i've had skin tags just below my bust for a while.i've suddenly found a purplish black one and it's not small...

well, at least i think it was a skin-tag. i've been scratching that area thinking it was a skin tag but when i looked down in the shower last night, i realized there was a big purplish coloured "blister" there. or could it be a mole? anyone know anything about these things?

?

oh.
it's a little bit itchy but not sure if it's just a blood blister..
