Well, yes and no. Trust me when I say this. Touching a cyst every 20 minutes just to make sure that its okay will make it 3 times as big, and twice as red.
I had a cyst on my chin that lasted for 3 weeks and became as big as a penny because I touched it so much. I got another cyst a few days ago. I never touched it, and put ice on it. This did the trick. The cyst isn't very noticeable now.
I know nothing about a girl's period (I'm a guy, what do you expect), but birth control pills may help you a lot.
I got cystic acne when I became pregnant with my son. It has never gone away and he's 16. I went on spironolactone a few years ago and it has helped a lot. I still got them every once in a while, but only a few times a year. It's worth looking into for females. The derm wanted me to do accutane or this.
