I have a mole that as long as I can remember has been on the back of my thigh. A couple of months ago the mole got a crust to it, I scratched it & it bleed (several times), then got to where it was raised with white "bits" that would come off like sand. Last week (5/16/11) I went to the Dr. and she froze it; it's still raised & it now looks like a blister, of sorts. The reason I'm here is that suddenly this afternoon (5/27/11), I'm having pain steming from the mole site up to the center of my butt cheek. The pain is deep within and it gets sharp & dull. Do you have any ideas? Thank you, Kim
