hello. i have had this bump in the middle of my crack, for 2 years, when i first got it, it was 2 sore, for me to bother, now its causing me pain, my doctor says its a blackhead, but it is deep. i put a hot towel on it, and had my husband try to squeeze it out, but he wasnt successful, im looking for ways to get it out, it is deep and old, when he would squeeze on it, a brown dried up residue, would slowly come out...please help. this is gross and painful
