Hey FibroGal, may I suggest you ask for a second opinion, even a third.
Here's the situation, you won't find less pain once you have your ovary removed, that is plain facts. I had a total hysterectomy, everything out, I had cancer of the right ovary, the left was full of cysts and before you get all excited, please don't think that because you have cysts that's you will get cancer of the ovary.
cysts are grown because your hormone are out of whack, quite clearly you need several medical opinions before undergoing the removal of the ovary.
What you may want to do is, seek a female gyno opinion to see what else you may try, such as hormone therapy, such as the pill, not all pills are the same, so you may find this alternative a little daunting, and it won't reduce you're pain at the drop of a few pills, actually it's a longer process.
You may want to stop eating red meats, and start eating loads of soya, yes, you are reading this right, there was a very good article today in the new television show Dr. Oz. so maybe you can catch it.
Having a hysterectory will not help you, nor having one ovary help you with the pain from intercourse, as of today, I am in my 50's I still have pain with having a relation with my hubby, and I was 23 when I was the victim of cancer.
You get your ovary removed, and what happens, do you honestly think that in 6 weeks recovery time you'll be all better and you'll have great sex, what happens, then if you are still experiencing pain, will your'e gyno tell you let's remove the second one also, all well since you won't have anything, will remove everything, you still are going to have pain. Then what, you would have done all this for nothing to gain from it.
Sure the gyno tells you there are nothing to back up his analysis also, he's a man, they don't know what a women goes through. Trust me as a women who went through so many gyno, operations, chimo, radiation, and hormones to last me a lifetime, with moods going up and down like an elevator, trust me you don't want to start that one.
Then he's say's there's nothing backing up the evidence about having your'e ovaries removed will increase heart desease, breast cancer and lung cancer, do you really want to risk it. I firmly believe that there is a corollation, I said it back when I was 23 and I'm still saying it today, finally some experts come up with it.
As I write this, I just went through getting two cysts removed in my right breast, my ducts activities where two lousy steps away from being declared cancerous, guess what, now I have to wait till december before the surgeon goes back in, my surgeon by the way is a women, and she even backs up the revolation that ovaries do play a big part in the women's life.
Get different opinions and go slow girl, yes, I understand it hurts having sex, but that can be accommodated with a sex therapist believe it or not.
Keep your head down, hold on to your heart, you'll be allright!, just go slowly in this process and get many opinion, and then slowly find your solutions.
We'll always be here for you girl!
