So a couple of months ago i had a mole on my leg that scabbed over and i picked the scab and it came off and looks fine now but i have discovered that a mole on my arm that i've had for as long as i remember now has an almost scab like black dot right on the edge, it definitely wasn't there before but the mole is pretty small.
i know i can't get a diagnosis here but any help would be great thanks :)
