I've gotten those horrible boils/cystic acne on my inner thigh/lower back a few times, and the absolute best remedy I ever found was to put a good amount of liquid echinacea on it, and cover it loosely with a bandaid if it doesn't hurt too much. Keep doing this throughout the day and at night before you go to bed. I thought it was too deep for any medicine to reach it, but within 24 hours, the entire cyst had become a whitehead that was painless to pop. (wow this description is kind of gross, but I know it works!)
