Are you getting your pap smears every year? In light of the dysplasia, it would be prudent to do so. 70% of cervical abnormalities are caused by HPV. As there is no cure for HPV.
Dysplasia can correct itself. The underlying problem is the HPV. It will never go away. Keep getting your pap smears. ~ This would not be connected to the pain you are having.
Hrm... You may want to ask the risks of birth control causing cancer on the birth control board. Carifairy is VERY knowledgable about all things birth control. I had never heard of it causing cancer.
Your best bet is going to be to go see a doctor about your cysts. The ER won't be of any help because they will only tell you to go see your regular physician for follow up. The ER isn't there to fix problems, they only treat the immediate issue.
You will need to find a gynecologist to help you.
Good luck!
