I had a bump on my face. It came up looking like a white head or pimple. I know I should not have mashed on it but I did. It is now raised and filled with fluid like a blood blister. It does not hurt. If I knock the top off it will bleed heavily. It seemed to try to heal after one heavy bleeding secession, but filled with fluid about a week later. It did not bleed as much this time as the last, and it is not as raised up. I have looked at skin cancer pictures on the net and can find nothing that even looks close to this. My friend thinks it might be a spider bite. I do have a dermotoligist appt. for April 3rd. I was hoping someone could give me some ideas on home treatment that might help. I have been applying neosporine with few results. It is smaller than a pencil erraser. I have also used drawing salve in the beginning.
