I had a small pink mole , was wearing fake fingernails scratched while asleep, after 3 weeks would crust and break away, saw my dr he squeezed it , come home looked like a blood blister. Scabs gets black comes off bleeds repeats, saw dr last week, been 3 months, he says it is now a cyst, it still bleeds and is attached like a dime sized skin tag, painful to touch. How do I get it to heal?
