Oh CT. Damnit, but at least they found the problem. I've had numerous overian cysts, and finally had the fucker removed when it became a tumor years later. I never regretted that at all, saved me from having those laparotomies every two years to clean house. (I had stinging/burning in my ass cheek, it was intense. I had pain into my upper legs, along with the cyst causing pain) Nerve bundles all over down there.
But it's important that you can walk, and get OUT OF PAIN. That's the most important thing, that you get better, and can get on with living your life like you used to.
Are you having surgery to pop it?
