**rolling eyes** Totally amazing to me how OBGYNS never NEVER (or at least in my experience) want to acknowledge the severe side effects caused from birth control.
It's not the pill that has caused the cyst. It's the fact that while ON the pill you didn't ovulate, and when you came off the pill your body attempted to ovulate and instead formed a cyst. Yes, they're painful, I know exactly what you're talking about. Some are worse than others. Most of them go away on their own after a week or so. I wouldn't be too concerned about it. Now, if you continue to get cysts regularly, you'll definitely want to let your doctor know. And if being back on BC is not what you want, don't let him talk you into it.
