Changes in mole, possible zit underneath?

I accidentally picked at a mole on my face since I thought it was a pimple and now it oozes and crusts over, the skin around the mole is red and feels inflamed. I feel a burning and stinging sensation right where the mole is and it feels hot. It seems raised instead of flush with the skin like it was before. Could it really just be a whitehead/zit underneath the mole or should I be concerened that it may be a sign of skin cancer? I have an appt with a dermatologist but it is not for another two weeks and I am anxious to know now.

Hey :)  I have one too on my scalp. I wear sunscreen ALL the time, but not on my scalp. I live in TN and the summers are painfully hot and humid, so I wear visors instead of a full hat, Plus I am going through menopause so I am already hot before I even walk out of my air conditioned home. About 6 weeks ago, right on the crown of my head, I got what I thought was a pimple. I did NOT squeeze it though. It is white in the middle and red around the edges and it won't go away. I have an appt. with a board certified dermatologist/surgeon (skin cancer specialist) today. I hope it's nothing. Please send me any prayers you can. I grew up in the 60's in Florida, in the sun a lot in the 70's too. Nobody warned me. I stopped laying in the sun by the time I was 24 and started using sunscreen. But they say you get %90 of your sun damage before your 18. Trying to keep positive.
